Fetchmail Release Notes ======================= This file is in Unicode charset with UTF-8 encoding. All dates are in Universal Time unless otherwise noted. (The `lines' figures total .c, .h, .l, and .y files under version control. Abbreviations in parentheses are the maintainers who committed the respective change. MA = Matthias Andree, ESR = Eric S. Raymond, RF = Rob Funk.) # ADVANCE WARNING OF FEATURES TO BE REMOVED OR CHANGED IN FUTURE VERSIONS (There are no plans to remove features from a 6.4.X release, but they may be removed from a 6.5.0 or newer release.) * Future fetchmail releases may require compilers and operating systems that adhere to standards issued 2011 or later. (Currently, C89 and Single Unix Specification V2 should suffice.) * Future fetchmail releases may tighten up security and lean towards it a bit more by, for instance, implementing recommendations from RFC-7817 or RFC-8314. This may, for instance, require that TLS v1.1 or newer be used. * The MX and host alias DNS lookups that fetchmail performs in multidrop mode are based on assumptions that are rarely met in practice, somewhat defective, deprecated and may be removed from a future fetchmail version. They have never supported IPv6 (including IPv6-mapped IPv4). Non-DNS based alias keywords such as "aka" will remain in fetchmail. * The monitor and interface options may be removed from a future fetchmail version as they are not reasonably portable across operating systems. * POP2 is obsolete, support will be removed from a future fetchmail version. * IMAP2 and IMAP4 (not IMAP4r1) are obsolete, support may be removed from a future fetchmail version. * RPOP is obsolete, support will be removed from a future fetchmail release. * The multidrop To/Cc guessing code along with the fragile duplicate suppressor is deprecated and may be removed from a future release. * The "envelope Received" option may be removed from a future release, because the Received header was never meant to be machine-readable, the format varies widely, and various other differences in behavior make parsing Received an unreliable undertaking. The envelope option as such will remain though, in order to support Delivered-To, X-Envelope-To, X-Original-To and similar. See also . * The --enable-fallback (fall back to MDA if MTA unavailable) will be removed from a future fetchmail release, because it makes fetchmail's behavior inconsistent and confusing. * The "protocol auto" default inside fetchmail may be removed from a future fetchmail release. Explicit configuration of the protocol is recommended. * Kerberos IV support may be removed from a future fetchmail release. * Kerberos 5 support may be removed from a future fetchmail release. * The --principal option may be removed from a future fetchmail release. * SIGHUP wakeup support may be removed from a future fetchmail release and cause fetchmail to terminate - it was broken for many years. * Support for operating systems that are not sufficiently POSIX compliant may be removed or operation on such systems may be suboptimal for future releases. This means that fetchmail may only continue to work on C99 and POSIX 2001 based systems. * The maintainer may migrate fetchmail to C++ with STL or C#, and impose further requirements (dependencies), such as Boost or other class libraries. * The softbounce option default will change to "false" in the next release. * The --bsmtp - mode of operation may be removed in a future release. * SSLv3 support may be removed from a future fetchmail release. It has been obsolete for many years and found insecure. Use TLS. * Fetchmailconf is deprecated and will be removed from a future release. * Fetchmail does not guarantee compatibility with EOL OpenSSL versions. Support for end-of-life OpenSSL versions may be removed even from patchlevel releases. * Nonstandard authentication schemes (such as RPA) may be removed from future fetchmail versions. * Nonstandard protocol extensions (such as SDPS/*ENV) may be removed from future fetchmail versions. * Future fetchmail releases (even minor ones) may change undocumented parts of the .netrc parser in incompatible ways to enhance compatibility with typical ftp(1) .netrc parsers. # KNOWN BUGS AND WORKAROUNDS * Fetchmail does not handle messages without Message-ID header well (See sourceforge.net bug #780933) * Fetchmail currently uses 31-bit signed integers in several places where unsigned and/or wider types should have been used, for instance, for mailbox sizes, and misreports sizes of 2 GibiB and beyond. Fixing this requires C89 compatibility to be relinquished. * BSMTP is mostly untested and errors can cause corrupt output. * Fetchmail does not track pending deletes across crashes. * The command line interface is sometimes a bit stubborn, for instance, fetchmail -s doesn't work with a daemon running. * Linux systems may return duplicates of an IP address in some circumstances if no or no global IPv6 addresses are configured. (No workaround. Ubuntu Bug#582585, Novell Bug#606980.) * Kerberos 5 may be broken, particularly on Heimdal, and provide bogus error messages. This will not be fixed, because the maintainer has no Kerberos 5 server to test against. Use GSSAPI. * For IMAP connections, fetchmail will print "will idle after poll" in verbose mode even though --idle is not given, as an artifact of the 6.4.22 security fixes. Fetchmail means "could idle after poll", but this would have required another loop through the translators. * aka ... hostnames are not considered for upstream server X.509 certificate verification, aka was meant for alias detection with multidrop mailboxes. * When compiled against wolfSSL, some diagnostics and messages of fetchmail are hardcoded to read "OpenSSL"; this was found only after the call for translations had been sent out already. -------------------------------------------------------------------------------- fetchmail-6.4.31 (released 2022-07-16, 31694 LoC): # BUG FIXES: * Try to fix ./configure --with-ssl=... for systems that have multiple OpenSSL versions installed. Issues reported by Dennis Putnam. * The netrc parser now reports its errors to syslog or logfile when appropriate, previously it would always log to stderr. * Add error checking to .netrc parser. # CHANGES: * manpage: use .UR/.UE macros instead of .URL for URIs. * manpage: fix contractions. Found with FreeBSD's igor tool. * manpage: HTML now built with pandoc -> python-docutils (manServer.pl was dropped) -------------------------------------------------------------------------------- fetchmail-6.4.30 (released 2022-04-26, 31666 LoC): # BREAKING CHANGES: * Bump wolfSSL minimum required version to 5.2.0 to pull in security fix. # CHANGES: * Using OpenSSL 1.* before 1.1.1n elicits a compile-time warning. * Using OpenSSL 3.* before 3.0.2 elicits a compile-time warning. * configure.ac was tweaked in order to hopefully fix cross-compilation issues report, and different patch suggested, by Fabrice Fontaine, https://gitlab.com/fetchmail/fetchmail/-/merge_requests/42 # TRANSLATIONS: language translations were updated by this fine person: * ro: Remus-Gabriel Chelu [Romanian] -------------------------------------------------------------------------------- fetchmail-6.4.29 (released 2022-03-20, 31661 LoC): # TRANSLATIONS: language translations were updated by this fine person: * vi: Trần Ngọc Quân [Vietnamese] -------------------------------------------------------------------------------- fetchmail-6.4.28 (released 2022-03-05, 31661 LoC): # DOCUMENTATION: * Fix a typo in the manual page, courtesy of Jeremy Petch. # TRANSLATIONS: language translations were updated by this fine person: * es: Cristian Othón Martínez Vera [Spanish] -------------------------------------------------------------------------------- fetchmail-6.4.27 (released 2022-01-26, 31661 LoC): # BREAKING CHANGES: * Bump wolfSSL minimum required version to 5.1.1 to pull in security fix. # TRANSLATIONS: language translations were updated by this fine person: * ro: Remus-Gabriel Chelu [Romanian] -------------------------------------------------------------------------------- fetchmail-6.4.26 (released 2021-12-26, 31661 LoC): # FIXES: * When using wolfSSL 5.0.0, work around a bug that appears to hit wolfSSL when receiving handshake records while still in SSL_peek(). Workaround is to read 1 byte and cache it, then call SSL_peek() again. This affects only some servers. https://github.com/wolfSSL/wolfssl/issues/4593 # TRANSLATIONS: language translations were updated by this fine person: * sr: Мирослав Николић (Miroslav Nikolić) [Serbian] -------------------------------------------------------------------------------- fetchmail-6.4.25 (released 2021-12-10, 31653 LoC): # BREAKING CHANGES: * Since distributions continue patching for LibreSSL use, which cannot be linked legally, block out LibreSSL in configure.ac and socket.c, and refer to COPYING, unless on OpenBSD (which ships it in the base system). OpenSSL and wolfSSL 5 can be used. SSL-related documentation was updated, do re-read COPYING, INSTALL, README, README.packaging, README.SSL. * Bump OpenSSL version requirement to 1.0.2f in order to safely remove the obsolete OpenSSL flag SSL_OP_SINGLE_DH_USE. This blocks out 1.0.2e and older 1.0.2 versions. 1.0.2f was a security fix release, and 1.0.2u is publicly available from https://www.openssl.org/source/old/1.0.2/ * Some of the configure.ac fiddling MIGHT have broken cross-compilation again. The maintainer does not test cross-compiling fetchmail; if you have difficulties, try setting PKG_CONFIG_LIBDIR to the pkg-config path containing your target/host libraries, or see if --with-ssl-prefix or --with-wolfssl-prefix, or overriding LDFLAGS/LIBS/CPPFLAGS, can help. Feedback solicited on compliant systems that are before end-of-life. # BUG FIXES: * 6.4.24's workaround for OpenSSL 1.0.2's X509_V_FLAG_TRUSTED_FIRST flag contained a typo and would not kick in properly. * Library and/or rpath setting from configure.ac was fixed. # ADDITIONS: * Added an example systemd unit file and instructions to contrib/systemd/ which runs fetchmail as a daemon with 5-minute poll intervals. Courteously contributed by Barak A. Pearlmutter, Debian Bug#981464. * fetchmail can now be used with wolfSSL 5's OpenSSL compatibility layer, see INSTALL and README.SSL. This is considered experimental. Feedback solicited. # CHANGES: * The getstats.py dist-tool now counts lines of .ac and .am files. * ./configure --with-ssl now supports pkg-config module names, too. See INSTALL. # TRANSLATIONS: language translations were updated by these fine people: (in reverse alphabetical order of language codes so as not to prefer people): * sv: Göran Uddeborg [Swedish] * sq: Besnik Bleta [Albanian] * pl: Jakub Bogusz [Polish] * ja: Takeshi Hamasaki [Japanese] * fr: Frédéric Marchal [French] * eo: Keith Bowes [Esperanto] * cs: Petr Pisar [Czech] # CREDITS: * Thanks to Corey Halpin for testing release candidates. -------------------------------------------------------------------------------- fetchmail-6.4.24 (released 2021-11-20, 30218 LoC): # OPENSSL AND LICENSING NOTE: > see fetchmail-6.4.22 below, and the file COPYING. Note that distribution of packages linked with LibreSSL is not feasible due to a missing GPLv2 clause 2(b) exception. # COMPATIBILITY: * Bison 3.8 dropped yytoknum altogether, breaking compilation due to a warning workaround. Remove the cast of yytoknum to void. This may cause a compiler warning to reappear with older Bison versions. * OpenSSL 1.0.2: Workaround for systems that keep the expired DST Root CA X3 certificate in its trust store because OpenSSL by default prefers the untrusted certificate and fails. Fetchmail now sets the X509_V_FLAG_TRUSTED_FIRST flag (on OpenSSL 1.0.2 only). This is workaround #2 from the OpenSSL Blog. For details, see both: https://www.openssl.org/blog/blog/2021/09/13/LetsEncryptRootCertExpire/ https://letsencrypt.org/docs/dst-root-ca-x3-expiration-september-2021/ NOTE: OpenSSL 1.0.2 is end of life, it is assumed that the OpenSSL library is kept up to date by a distributor or via OpenSSL support contract. Where this is not the case, please upgrade to a supported OpenSSL version. # DOCUMENTATION: * The manual page was revised after re-checking with mandoc -Tlint, aspell, igor. Some more revisions were made for clarity. # TRANSLATIONS: language translations were updated by these fine people: * sv: Göran Uddeborg [Swedish] * pl: Jakub Bogusz [Polish] * fr: Frédéric Marchal [French] * cs: Petr Pisar [Czech] * eo: Keith Bowes [Esperanto] * ja: Takeshi Hamasaki [Japanese] -------------------------------------------------------------------------------- fetchmail-6.4.23 (released 2021-10-31, 30206 LoC): # USABILITY: * For common ssh-based IMAP PREAUTH setups (i. e. those that use a plugin - no matter its contents - and that set auth ssh), change the STARTTLS error message to suggest sslproto '' instead. This is a commonly reported issue after the CVE-2021-39272 fix in 6.4.22. Fixes Redhat Bugzilla 2008160. Fixes GitLab #39. # TRANSLATIONS: language translations were updated by these fine people: * ja: Takeshi Hamasaki [Japanese] * sr: Мирослав Николић (Miroslav Nikolić) [Serbian] -------------------------------------------------------------------------------- fetchmail-6.4.22 (released 2021-09-13, 30201 LoC): # OPENSSL AND LICENSING NOTE: * fetchmail 6.4.22 is compatible with OpenSSL 1.1.1 and 3.0.0. OpenSSL's licensing changed between these releases from dual OpenSSL/SSLeay license to Apache License v2.0, which is considered incompatible with GPL v2 by the FSF. For implications and details, see the file COPYING. # SECURITY FIXES: * CVE-2021-39272: fetchmail-SA-2021-02: On IMAP connections, without --ssl and with nonempty --sslproto, meaning that fetchmail is to enforce TLS, and when the server or an attacker sends a PREAUTH greeting, fetchmail used to continue an unencrypted connection. Now, log the error and abort the connection. --Recommendation for servers that support SSL/TLS-wrapped or "implicit" mode on a dedicated port (default 993): use --ssl, or the ssl user option in an rcfile. --Reported by: Andrew C. Aitchison, based on the USENIX Security 21 paper "Why TLS is better without STARTTLS - A Security Analysis of STARTTLS in the Email Context" by Damian Poddebniak, Fabian Ising, Hanno Böck, and Sebastian Schinzel. The paper did not mention fetchmail. * On IMAP and POP3 connections, --auth ssh no longer prevents STARTTLS negotiation. * On IMAP connections, fetchmail does not permit overriding a server-side LOGINDISABLED with --auth password any more. * On POP3 connections, the possibility for RPA authentication (by probing with an AUTH command without arguments) no longer prevents STARTTLS negotiation. * For POP3 connections, only attempt RPA if the authentication type is "any". # BUG FIXES: * On IMAP connections, when AUTHENTICATE EXTERNAL fails and we have received the tagged (= final) response, do not send "*". * On IMAP connections, AUTHENTICATE EXTERNAL without username will properly send a "=" for protocol compliance. * On IMAP connections, AUTHENTICATE EXTERNAL will now check if the server advertised SASL-IR (RFC-4959) support and otherwise refuse (fetchmail <= 6.4 has not supported and does not support the separate challenge/response with command continuation) * On IMAP connections, when --auth external is requested but not advertised by the server, log a proper error message. * Fetchmail no longer crashes when attempting a connection with --plugin "" or --plugout "". * Fetchmail no longer leaks memory when processing the arguments of --plugin or --plugout on connections. * On POP3 connections, the CAPAbilities parser is now caseblind. * Fix segfault on configurations with "defaults ... no envelope". Reported by Bjørn Mork. Fixes Debian Bug#992400. This is a regression in fetchmail 6.4.3 and happened when plugging memory leaks, which did not account for that the envelope parameter is special when set as "no envelope". The segfault happens in a constant strlen(-1), triggered by trusted local input => no vulnerability. * Fix program abort (SIGABRT) with "internal error" when invalid sslproto is given with OpenSSL 1.1.0 API compatible SSL implementations. # CHANGES: * IMAP: When fetchmail is in not-authenticated state and the server volunteers CAPABILITY information, use it and do not re-probe. (After STARTTLS, fetchmail must and will re-probe explicitly.) * For typical POP3/IMAP ports 110, 143, 993, 995, if port and --ssl option do not match, emit a warning and continue. Closes Gitlab #31. (cherry-picked from 6.5 beta branch "legacy_6x") * fetchmail.man and README.SSL were updated in line with RFC-8314/8996/8997 recommendations to prefer Implicit TLS (--ssl/ssl) and TLS v1.2 or newer, placing --sslproto tls1.2+ more prominently. The defaults shall not change between 6.4.X releases for compatibility. # TRANSLATIONS: language translations were updated by these fine people: * sq: Besnik Bleta [Albanian] * cs: Petr Pisar [Czech] * eo: Keith Bowes [Esperanto] * fr: Frédéric Marchal [French] * pl: Jakub Bogusz [Polish] * sv: Göran Uddeborg [Swedish] # CREDITS: * Thanks for testing the release candidates and bug reports to: Corey Halpin, Stefan Eßer. -------------------------------------------------------------------------------- fetchmail-6.4.21 (released 2021-08-09, 30042 LoC): # REGRESSION FIX: * The new security fix in 6.4.20 for CVE-2021-36386 caused truncation of messages logged to buffered outputs, from --logfile and --syslog. This also caused lines in the logfile to run into one another because the fragment containing the '\n' line-end character was usually lost. Reason is that on all modern systems (with header and vsnprintf() interface), the length of log message fragments was added up twice, so that these ended too deep into a freshly allocated buffer, after the '\0' byte. Unbuffered outputs flushed the fragments right away, which masked the bug. Reported by: Jürgen Edner, Erik Christiansen. -------------------------------------------------------------------------------- fetchmail-6.4.20 (released 2021-07-28, 30042 LoC): # SECURITY FIX: * When a log message exceeds c. 2 kByte in size, for instance, with very long header contents, and depending on verbosity option, fetchmail can crash or misreport each first log message that requires a buffer reallocation. fetchmail then reallocates memory and re-runs vsnprintf() without another call to va_start(), so it reads garbage. The exact impact depends on many factors around the compiler and operating system configurations used and the implementation details of the stdarg.h interfaces of the two functions mentioned before. To fix CVE-2021-36386. Reported by Christian Herdtweck of Intra2net AG, Tübingen, Germany. He also offered a patch, which I could not take for fetchmail 6.4 because it required a C99 system and I'd promised earlier that 6.4 would remain compatible with C89 systems. -------------------------------------------------------------------------------- fetchmail-6.4.19 (released 2021-04-24, 30026 LoC): # CHANGE: * fetchmailconf: properly catch and report option parsing errors # BUG FIX: * LMTP: do not try to validate the last component of a UNIX-domain LMTP socket as though it were a TCP port. Reported by Christoph Heitkamp, Gitlab issue #33. # TRANSLATION UPDATE: This fine person has contributed an updated translation: * sr: Мирослав Николић (Miroslav Nikolić) [Serbian] -------------------------------------------------------------------------------- fetchmail-6.4.18 (released 2021-03-27, 30011 LoC): # REGRESSION FIX: * fetchmailconf: fetchmail 6.4.16 added --sslcertfile to the configuration dump, but fetchmailconf support was incomplete in Git 7349f124 and it could not parse sslcertfile, thus the user settings editor came up empty with console errors printed. Fix configuration parser in fetchmailconf. # ROBUSTNESS FIXES: * fetchmailconf: do not require fetchmail for -V. do not require Tk (Tkinter) for -d option. This is to fail more gracefully on incomplete installs. * TLS code: remove OPENSSL_NO_DEPRECATED macros to avoid portability issues with OpenSSL v3 - these are for development purposes, not production. * TLS futureproofing: use SSL_use_PrivateKey_file instead of SSL_use_RSAPrivateKey_file, the latter will be deprecated with OpenSSL v3, and the user's key file might be something else than RSA. # TRANSLATION UPDATE: This fine person has contributed an updated translation: * fi: Lauri Nurmi [Finnish] -------------------------------------------------------------------------------- fetchmail-6.4.17 (released 2021-03-07, 29998 LoC): # BUG FIXES * IMAP client: it used to leak memory for username and password when trying the LOGIN (password-based) authentication and encountered a timeout situation. * dist-tools/getstats.py: also counts lines in *.py files, shown above. # CHANGES * fetchmail.man: now mentions that you may need to add --ssl when specifying a TLS-wrapped port. * fetchmailconf: --version (-V) now prints the Python version in use. # TRANSLATION UPDATE: This fine person has contributed an updated translation: * ja: Takeshi Hamasaki [Japanese] -------------------------------------------------------------------------------- fetchmail-6.4.16 (released 2021-02-08, 27707 LoC): # BUG FIXES * fetchmail's --configdump, and fetchmailconf, lacked support for the sslcertfile option. --configdump support added by Earl Chew, Gitlab issue #25, merge request !28. * fetchmail's manual page was never updated to reflect 6.2.5's change about the duplicate-killer code for multidrop mode, which read "* Dup-killer code now keys on an MD5 hash of the raw headers." ...instead of just the Message-ID. [commit 9dd8400, 2003-10-10 by esr] The manual page was now updated accordingly and documents historic behaviour: start to 5.0.7 no duplicate suppression; 5.0.8 to 6.2.4 duplicate suppression only by Message-ID; 6.2.5 to 6.4.X duplicate suppression by entire raw header. Manpage bug found by Julian Bane debugging "duplicate message" behaviour. * ./configure no longer runs AC_LIB_LINKFLAGS (how to link) checks when called --without-ssl # FEATURES * fetchmail --version [fetchmail -V] now queries and prints the SSL/TLS library's "SSL default trusted certificate" file or directory (mind the word "default"), where the OpenSSL-compatible TLS implementation will look for trusted root, meaning certification authority (CA), certificates. NOTE 1: watch the output carefully if the line prints the defaults or the configured path (without "default"). NOTE 2: SSL_CERT_DIR and SSL_CERT_FILE are documented environment variables for OpenSSL 1.1.1 to override the *default* locations (those compiled into OpenSSL or possibly in its configuration file). This was added when Gene Heskett was debugging his setup and the information "where does OpenSSL look" was missing. * fetchmail --version now prints version of the OpenSSL library that it was compiled against, and that it is using at runtime, and also the OPENSSL_DIR and OPENSSL_ENGINES_DIR (if available). # TRANSLATION UPDATES These fine people have contributed updated translations for fetchmail, in no particular order: * sq: Besnik Bleta [Albanian] * eo: Keith Bowes [Esperanto] * cs: Petr Pisar [Czech] * pl: Jakub Bogusz [Polish] * sv: Göran Uddeborg [Swedish] * fr: Frédéric Marchal [French] --------------------------------------------------------------------------------- fetchmail-6.4.15 (released 2021-01-03, 27614 LoC): # BUG FIXES * Fix a typo in the manual page reported by David McKelvie. * Fix cross-compilation with openssl, by Fabrice Fontaine. Merge request !23. * Fix truncation of SMTP PLAIN AUTH with ^ in credentials, by Earl Chew. Gitlab issue #23, merge request !25. ------------------------------------------------------------------------------- fetchmail-6.4.14 (released 2020-11-26, 27608 LoC): # TRANSLATION UPDATES were made by these fine people: * sr: Мирослав Николић (Miroslav Nikolić) [Serbian] --------------------------------------------------------------------------------- fetchmail-6.4.13 (released 2020-10-25, 27608 LoC): # BUG FIXES: * Errors about lock file (= pidfile) creation could be lost in daemon configurations (-d option, or set daemon) when using syslog. Now they are also logged to syslog. Found verifying a pidfile creation issue on 6.4.12 that was previously reported by Alex Hall of Automatic Distributors. * If the lock file cannot be removed (no write permission on directory), try to truncate it, and if that fails, report error. * If the pidfile was non-default, fetchmail -q or --quit would malfunction and claim no other fetchmail were running, because it did not read the configuration files or merge the command line options, thus it would look for the PID in the wrong file. # CHANGES: * Lockfile (= pidfile) creation errors are now logged with filename and reason. # TRANSLATION UPDATES were made by these fine people: * cs: Petr Pisar [Czech] * ja: Takeshi Hamasaki [Japanese] * sq: Besnik Bleta [Albanian] * zh_CN: Boyuan Yang [Chinese (simplified)] * sv: Göran Uddeborg [Swedish] * pl: Jakub Bogusz [Polish] * fr: Frédéric Marchal [French] * eo: Keith Bowes [Esperanto] * de: [German - by current maintainer] --------------------------------------------------------------------------------- fetchmail-6.4.12 (released 2020-09-04, 27596 LoC): # BUG FIXES: * The README file is now the one from Git again. The makerelease.pl script used to roll and upload the tarball sometimes clobbered the README file and replaced its contents by a part of the NEWS file. --------------------------------------------------------------------------------- fetchmail-6.4.11 (released 2020-08-28, 27596 LoC): # REGRESSION FIX: * configure: fetchmail 6.4.9 and 6.4.10 would miss checking for TLS v1.2 and TLS v1.3 support if AC_LIB_LINKFLAGS came up with something such as /path/to/libssl.so, rather than -lssl. (For instance on FreeBSD) --------------------------------------------------------------------------------- fetchmail-6.4.10 (released 2020-08-27, 27596 LoC): # REGRESSION FIX: * configure: fetchmail 6.4.9's configure was unable to pick up OpenSSL if it wasn't announced by pkg-config, for instance, on FreeBSD. --------------------------------------------------------------------------------- fetchmail-6.4.9: (not announced by e-mail, withdrawn) ## DOCUMENTATION UPDATE: * manpage: mention that the SSL/TLS certificate fingerprint uses an MD5 hash. ## CHANGES: * configure: try to use AC_LIB_LINKFLAGS to obtain proper link flags for libcrypto and libssl if pkg-config failed. This is an attempt to fix borderline issues when users building on systems with obsolete OpenSSL try to use a local newer OpenSSL from a separate directory. ## NEW TRANSLATION, with thanks to the translator: * ro: Florentina Mușat [Romanian] --------------------------------------------------------------------------------- fetchmail-6.4.8 (released 2020-06-14, 27596 LoC): ## NEW TRANSLATION, with thanks to the translator: * sr: Мирослав Николић (Miroslav Nikolić) [Serbian] - Sorry, this was missed earlier because my translation scripts did not properly report new translations. --------------------------------------------------------------------------------- fetchmail-6.4.7 (released 2020-06-14, 27596 LoC): ## TRANSLATION UPDATE, with thanks to the translator: * sv: Göran Uddeborg [Swedish] ------------------------------------------------------------------------------- fetchmail-6.4.6 (released 2020-05-29, 27596 LoC): ## TRANSLATION UPDATE, with thanks to the translator: * eo: Felipe Castro [Esperanto] -------------------------------------------------------------------------------- fetchmail-6.4.5 (released 2020-05-07, 27596 LoC): ## REGRESSION FIX: * fetchmail 6.4.0 and 6.4.1 changed the resolution of the home directory in a way that requires SUSv4 semantics of realpath(), which leads to 'Cannot find absolute path for... directory' error messages followed by aborts on systems where realpath() follows strict SUSv2 semantics and returns EINVAL if the 2nd argument is NULL. On such systems, for instance, Solaris 10, fetchmail requires PATH_MAX to be defined, and will then work again. Regression reported by David Hough. On systems that neither provide auto-allocation semantics for realpath(), nor PATH_MAX, fetchmail will print this error and abort. Such systems are unsupported, see README. ## CHANGES: * Add a test program fm_realpath, and a t.realpath script, neither to be installed. These will test resolution of the current working directory. ## TRANSLATION UPDATES in reverse alphabetical order of language codes, ## with my thanks to the translators: * zh_CN: Boyuan Yang [Chinese (simplified)] * sv: Göran Uddeborg [Swedish] * sq: Besnik Bleta [Albanian] * pl: Jakub Bogusz [Polish] * ja: Takeshi Hamasaki [Japanese] * fr: Frédéric Marchal [French] * cs: Petr Pisar [Czech] -------------------------------------------------------------------------------- fetchmail-6.4.4 (released 2020-04-26, 27530 LoC): ## UPDATED TRANSLATIONS - WITH THANKS TO THE TRANSLATOR: * ja: Takeshi Hamasaki [Japanese] -------------------------------------------------------------------------------- fetchmail-6.4.3 (released 2020-04-05, 27530 LoC): ## BUGFIXES: * Plug memory leaks when parts of the configuration (defaults, rcfile, command line) override one another. * Merge esmtpname and esmtppassword defaults properly. * fetchmail terminated the placeholder command string too late and included garbage from the heap at the end of the string. Workaround: don't use place- holders %h or %p in the --plugin string. Bug added in 6.4.0 when merging Gitlab merge request !5 in order to fix an input buffer overrun. Faulty commit 418cda65f752e367fa663fd13884a45fcbc39ddd. Reported by Stefan Thurner, Gitlab issue #16. * Fetchmail now checks for errors when trying to read the .idfile, Gitlab issue #3. * Fetchmail's error messages that reports that the defaults entry isn't the first was made more precise. It could be misleading if there was a poll or skip statement before the defaults. ## CHANGES: * Fetchmail documentation was updated to require OpenSSL 1.1.1. OpenSSL 1.0.2 reached End Of Life status at the end of the year 2019. Fetchmail will tolerate, but warn about, 1.0.2 for now on the assumption that distributors backport security fixes as the need arises. Fetchmail will also warn if another SSL library that is API-compatible with OpenSSL lacks TLS v1.3 support. * If the trust anchor is missing, fetchmail refers the user to README.SSL. ## INTERNAL CHANGES: * The AC_DECLS(getenv) check was removed, its only user was broken and not accounting for that AC_DECLS always defines HAVE_DECL_... to 0 or 1, so fetchmail never declared a missing getenv() symbol (it was testing with #ifdef). Remove the backup declaration. getenv is mandated by SUSv2 anyways. ## UPDATED TRANSLATIONS - WITH THANKS TO THE TRANSLATORS: * sq: Besnik Bleta [Albanian] * zh_CN: Boyuan Yang [Chinese (simplified)] * pl: Jakub Bogusz [Polish] * cs: Petr Pisar [Czech] * fr: Frédéric Marchal [French] * sv: Göran Uddeborg [Swedish] * eo: Felipe Castro [Esperanto] -------------------------------------------------------------------------------- fetchmail-6.4.2 (released 2020-02-14, 27473 LoC): ## BREAKING CHANGES: * fetchmailconf now supports Python 3 and currently requires the "future" package, see https://pypi.org/project/future/. * fetchmailconf: The minimum supported version is now Python 2.7.13, but it is recommended to use at least 2.7.16 (due to its massive SSL updates). Older Python versions may check SSL certificates not strictly enough, which may cause fetchmail to complain later, if the certificate verify fails. * fetchmailconf now autoprobes SSL-wrapped connections (ports 993 and 995 for IMAP and POP3) as well and by preference. * fetchmailconf now defaults newly created users to "ssl" if either of the existing users sets ssl, or if the server has freshly been probed and found supporting ssl. There is a caveat: adding a user to an existing server without probing it again may skip adding ssl. (This does not prevent STARTTLS.) ## BUG FIXES: * Fix three bugs in fetchmail.man (one unterminated string to .IP macro, one line that ran into a .PP macro, .TH date format), and remove one .br request from inside the table, which is unsupported by FreeBSD 12's mandoc(1) formatter. FreeBSD Bug#241032, reported by Helge Oldach. * Further man page fixes and additions by Chris Mayo and Gregor Zattler. * When evaluating the need for STARTTLS in non-default configurations (SSL certificate validation turned off), fetchmail would only consider --sslproto tls1 as requiring STARTTLS, now all non-empty protocol versions do. * fetchmailconf now properly writes "no sslcertck" if sslcertck is disabled. * fetchmailconf now catches and reports OS errors (including DNS errors) when autoprobing. Reported as Gitlab issue #12 by Sergey Alirzaev. * fetchmailconf received a host of other bugfixes, see the Git commit log. ## CHANGES: * Make t.smoke more robust and use temporary directory as FETCHMAILHOME, to make sure that the home directory resolves for the user running the test suite even if the environment isn't perfect. Reported by Konstantin Belousov, analysed by Corey Halpin, FreeBSD Bug#240914. ## UPDATED TRANSLATION - THANKS TO: * zh_CN: Boyuan Yang [Chinese (simplified)] -------------------------------------------------------------------------------- fetchmail 6.4.1 (released 2019-09-28, 27473 LoC): ## REGRESSION FIXES: * The bug fix Debian Bug#941129 was incomplete and caused + a regression in the default file locations, so that fetchmail was no longer able to find its configuration files in some situations. Reported by Cy Schubert, Christian Ebert. + a regression under _FORTIFY_SOURCE where PATH_MAX > minimal _POSIX_PATH_MAX. -------------------------------------------------------------------------------- fetchmail 6.4.0 (released 2019-09-27, 27429 LoC): # NOTE THAT FETCHMAIL IS NO LONGER PUBLISHED THROUGH IBIBLIO. * They have stopped accepting submissions and consider themselves an archive. ## SECURITY FIXES THAT AFFECT BEHAVIOUR AND MAY REQUIRE RECONFIGURATION * Fetchmail no longer supports SSLv2. * Fetchmail no longer attempts to negotiate SSLv3 by default, even with --sslproto ssl23. Fetchmail can now use SSLv3, or TLSv1.1 or a newer TLS version, with STLS/STARTTLS (it would previously force TLSv1.0 with STARTTLS). If the OpenSSL version used at build and run-time supports these versions, --sslproto ssl3 and --sslproto ssl3+ can be used to re-enable SSLv3. Doing so is discouraged because the SSLv3 protocol is broken. Along the lines suggested - as patch - by Kurt Roeckx, Debian Bug #768843. While this change is supposed to be compatible with common configurations, users may have to and are advised to change all explicit --sslproto ssl2 (change to newer protocols required), --sslproto ssl3, --sslproto tls1 to --sslproto auto, so that they can benefit from TLSv1.1 and TLSv1.2 where supported by the server. The --sslproto option now understands the values auto, ssl3+, tls1+, tls1.1, tls1.1+, tls1.2, tls1.2+, tls1.3, tls1.3+ (case insensitively), see CHANGES below for details. * Fetchmail defaults to --sslcertck behaviour. A new option --nosslcertck to override this has been added, but may be removed in future fetchmail versions in favour of another configuration option that makes the insecurity in using this option clearer. ## SECURITY FIXES * Fetchmail prevents buffer overruns in GSSAPI authentication with user names beyond c. 6000 characters in length. Reported by Greg Hudson. ## CHANGED REQUIREMENTS * fetchmail 6.4.0 is written in C99 and requires a SUSv3 (Single Unix Specification v3, a superset of POSIX.1-2001 aka. IEEE Std 1003.1-2001 with XSI extension) compliant system. For now, a C89 compiler should also work if the system is SUSv3 compliant. In particular, older fetchmail versions had workaround for several functions standardized in the Single Unix Specification v3, these have been removed. The trio/ library has been removed from the distribution. ## CHANGES * fetchmail 6.3.X is unsupported. * fetchmail now configures OpenSSL support by default. * fetchmail now requires OpenSSL v1.0.2 or newer. * Fetchmail now supports --sslproto auto and --sslproto tls1+ (same as ssl23). * --sslproto tls1.1+, tls1.2+, and tls1.3+ are now supported for auto-negotiation with a minimum specified TLS protocol version, and --sslproto tls1.1, --sslproto tls1.2 and --sslproto tls1.3 to force the specified TLS protocol version. Note that tls1.3 requires OpenSSL v1.1.1 or newer. * Fetchmail now detects if the server hangs up prematurely during SSL_connect() and reports this condition as such, and not just as SSL connection failure. (OpenSSL 1.0.2 reported incompatible with pop3.live.com by Jerry Seibert). * A foreground fetchmail can now accept a few more options while another copy is running in the background. * fetchmail now handles POP3 --keep UID lists more efficiently, by using Rainer Weikusat's P-Tree implementation. This reduces the complexity for handling a large UIDL from O(n^2) to O(n log n) and becomes noticably faster with thousands of kept messages. (IMAP does not currently track UIDs and is unaffected.) At the same time, the UIDL emulation code for deficient servers has been removed. It never worked really well. Servers that do not implement the optional UIDL command only work with --fetchall option set, which in itself is incompatible with the --keep option (it would cause message duplication). * fetchmail, when setting up TLS connections, now uses SSL_set_tlsext_host_name() to set up the SNI (Server Name Indication). Some servers (for instance googlemail) require SNI when using newer SSL protocols. * Fetchmail now sets the expected hostname through OpenSSL 1.0.2's new X509_VERIFY_PARAM_set1_host() function to enable OpenSSL's native certificate verification features. * fetchmail will drop the connection when fetching with IMAP and receiving an unexpected untagged "* BYE" response, to work around certain faulty servers. * The FETCHMAIL_POP3_FORCE_RETR environment variable is now documented, it forces fetchmail, when talking POP3, to always use the RETR command, even if it would otherwise use the TOP command. * Fetchmail's configure stage will try to query pkg-config or pkgconf for libssl and libcrypto, in case other system use .pc files to document specific library dependencies. (contributed by Fabrice Fontaine, GitLab merge request !14.) * The gethostbyname() API calls and compatibility functions have been removed. * These translations are shipped but not installed by default because they have less than 500 translated messages out of 714: el fi gl pt_BR sk tr -> Greek, Finnish, Galician, Brazilian Portuguese, Slovak, Turkish. * Fetchmail now refuses delivery if the MDA option contains single-quoted expansions. Fixes Debian Bug#347909. ## FIXES * Fix a typo in the FAQ. Submitted by David Lawyer, Debian Bug#706776. * Do not translate header tags such as "Subject:". Reported by Gonzalo Pérez de Olaguer Córdoba, Debian Bug#744907. * Convert most links from berlios.de to sourceforge.net. * Report error to stderr, and exit, if --idle is combined with multiple accounts. * Point to --idle from GENERAL OPERATION to clarify --idle and multiple mailboxes do not mix. In response to Jeremy Chadwick's trouble 2014-11-19, fetchmail-users mailing list. * Fix SSL-enabled build on systems that do not declare SSLv3_client_method(), or that #define OPENSSL_NO_SSL3 inside #include Related to Debian Bug#775255. Fixes Debian Bug #804604. * Version report lists -SSLv3 on SSL-enabled no-ssl3 builds. * Fetchmail no longer adds a NUL byte to the username in GSSAPI authentication. This was reported to break Kerberos-based authentication with Microsoft Exchange 2013 by Greg Hudson. * Set umask properly before writing the .fetchids file, to avoid failing the security check on the next run. Reported by Fabian Raab, Fixes Debian Bug#831611. * When forwarding by LMTP, also check antispam response code when collecting the responses after the CR LF . CR LF sequence at the end of the DATA phase. (Contributed by Evil.2000, GitLab merge request !12.) * fetchmail will not try other protocols after a socket error. This avoids mismatches of how different prococols see messages as "seen" and re-fetches of known mail. (Fix contributed by Lauri Nurmi, GitLab Merge Request !10.) * fetchmail no longer reports "System error during SSL_connect(): Success." Fixes Debian Bug#928916, reported by Paul Kimoto. * fetchmailconf would ignore Edit or Delete actions on the first (topmost) item in a list (no matter if server list, user list, ...). * The mimedecode feature now properly detects multipart/mixed-type matches, so that quoted-printable-encoded multipart messages can get decoded. (Regression in 5.0.0 on 1999-03-27, as a side effect of a PGP-mimedecode fix attributed to Henrik Storner.) * FETCHMAILHOME can now safely be a relative path, which will be qualified through realpath(). Previously, it had to be absolute in daemon mode. Reported by Alex Andreotti, Debian Bug#941129. ## UPDATED TRANSLATIONS - THANKS TO: * CS: Petr Pisar [Czech] * EO: Felipe Castro [Esperanto] * FR: Frédéric Marchal [French] * JP: Takeshi Hamasaki [Japanese] * PL: Jakub Bogusz [Polish] * SV: Göran Uddeborg [Swedish] -------------------------------------------------------------------------------- fetchmail-6.3.26 (released 2013-04-23, 26180 LoC): # CRITICAL BUG FIX for setups using "mimedecode": * The mimedecode feature failed to ship the last line of the body if it was encoded as quoted-printable and had a MIME soft line break in the very last line. Reported by Lars Hecking in June 2011. Bug introduced on 1998-03-20 when the mimedecode support was added by ESR before release 4.4.1 through code contributed by Henrik Storner. Workaround for older releases: do not use mimedecode feature. Earlier versions of this NEWS file claimed this bug fixed in fetchmail-6.3.23, but it was not. Fixes Launchpad Bug#1171818. fetchmail-6.3.25 (released 2013-03-18, 26149 LoC): # BUG FIXES * Fix a memory leak in out-of-memory error condition while handling plugins. Report and patch by John Beck (found with Parfait static code analyzer). * Fix a NULL pointer dereference in out-of-memory error condition while handling plugins. Report and patch by John Beck (found with Parfait static code analyzer). # CHANGES * Improved reporting when SSL/TLS X.509 certificate validation has failed, working around a not-so-recent swapping of two OpenSSL error codes, and a practical impossibility to distinguish broken certification chains from missing trust anchors (root certificates). * OpenSSL decoded errors are now reported through report(), rather than dumped to stderr, so that they should show up in logfiles and/or syslog. * The fetchmail manual page no longer claims that MD5 were the default OpenSSL hash format (for use with --sslfingerprint). Reported by Jakob Wilk, PARTIAL fix for Debian Bug#700266. * The fetchmail manual page now refers the user to --softbounce from the SMTP/ESMTP ERROR HANDLING section. Reported by Anton Shterenlikht. # WORKAROUNDS * Older systems that provide the older RFC-2553 implementation of getaddrinfo, rather than the current RFC-3493, and systems that do not provide this getaddrinfo() interface at all and thus use the replacement functions from libesmtp/getaddrinfo.?, might return EAI_NODATA when a host is registered in DNS as MX or similar, but without A or AAAA records. Handle this situation when checking for multidrop aliases and treat EAI_NODATA the same as EAI_NONAME, i. e. name cannot be resolved. The proper fix, however, is to upgrade the operating system. # TRANSLATION UPDATES [cs] Czech, by Petr Pisar [da] Danish, by Joe Hansen [de] German [eo] Esperanto, by Sian Mountbatten and Felipe Castro [fr] French, by Frédéric Marchal [ja] Japanese, by Takeshi Hamasaki [pl] Polish, by Jakub Bogusz [sv] Swedish, by Göran Uddeborg [vi] Vietnamese, by Trần Ngọc Quân fetchmail-6.3.24 (released 2012-12-23, 26108 LoC): # CRITICAL AND REGRESSION FIXES * Plug a memory leak in OpenSSL's certificate verification callback. This would affect fetchmail configurations running with SSL in daemon mode more than one-shot runs. Reported by Erik Thiele, and pinned by Dominik Heeg, fixes Debian Bug #688015. This bug was introduced into fetchmail 6.3.0 (committed 2005-10-29) when support for subjectAltName was added through a patch by Roland Stigge, submitted as Debian Bug#201113. * The --logfile option now works again outside daemon mode, reported by Heinz Diehl. The documentation that I had been reading was inconsistent with the code, and only parts of the manual page claimed that --logfile was only effective in daemon mode. fetchmail-6.3.23 (released 2012-12-10, 26106 LoC): # REGRESSION FIXES * Fix compilation with OpenSSL implementations before 0.9.8m that lack SSL_CTX_clear_options. Patch by Earl Chew. Note that the use of older OpenSSL versions with fetchmail is unsupported and *not* recommended. # BUG FIXES * Fix combination of --plugin and -f -. Patch by Alexander Zangerl, to fix Debian Bug#671294. * Clean up logfile vs. syslog handling, and in case logfile overrides syslog, send a message to the latter stating where logging goes. # CHANGES * The build process can now be made a bit more silent and concise through ./configure --enable-silent-rules, or by adding "V=0" to the make command. # WORKAROUNDS * Make Maillennium POP3 workarounds less specific, to encompass Maillennium POP3/UNIBOX (Maillennium V05.00c++).

Also, with a carefully crafted NTLM challenge packet sent from the server, it would be possible that fetchmail conveyed confidential data not meant for the server through the NTLM response packet. Fix: Detect base64 decoding errors, validate the NTLM challenge, and abort NTLM authentication in case of error. See fetchmail-SA-2012-02.txt for further details. Reported by J. Porter Clark. * for CVE-2011-3389: SSL/TLS (wrapped and STARTTLS): fetchmail used to disable a countermeasure against a certain kind of attack against cipher block chaining initialization vectors (SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS). Whether this creates an exploitable situation, depends on the server and the negotiated ciphers. As a precaution, fetchmail 6.3.22 enables the countermeasure, by clearing SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS. NOTE that this can cause connections to certain non-conforming servers to fail, in which case you can set the environment variable FETCHMAIL_DISABLE_CBC_IV_COUNTERMEASURE to any non-empty value when starting fetchmail to re-instate the compatibility option at the expense of security. Reported by Apple Product Security. For technical details, refer to . See fetchmail-SA-2012-01.txt for further details. # BUG FIX * The Server certificate: message in verbose mode now appears on stdout like the remainder of the output. Reported by Henry Jensen, to fix Debian Bug #639807. * The GSSAPI-related autoconf code now matches gssapi.c better, and uses a different check to look for GSS_C_NT_HOSTBASED_SERVICE. This fixes the GSSAPI-enabled build on NetBSD 6 Beta. # CHANGES * On systems where SSLv2_client_method isn't defined in OpenSSL (such as newer Debian, and Ubuntu starting with 11.10 oneiric ocelot), don't reference it (to fix the build) and if configured, print a run-time error that the OS does not support SSLv2. Fixes Debian Bug #622054, but note that that bug report has a more thorough patch that does away with SSLv2 altogether. * The security and errata notices fetchmail-{EN,SA}-20??-??.txt are now under the more relaxed CC BY-ND 3.0 license (the noncommercial clause was dropped). The Creative Commons address was updated. * The Python-related Makefile.am parts were simplified to avoid an automake 1.11.X bug around noinst_PYTHON, Automake Bug #10995. * Configuring fetchmail without SSL now triggers a configure warning, and asks the user to consider running configure --with-ssl. # WORKAROUND * Some servers, notably Zimbra, return A1234 987 FETCH () in response to a header request, in the face of message corruption. fetchmail now treats these as temporary errors. Report and Patch by Mikulas Patocka, Red Hat. * Some servers, notably Microsoft Exchange, return "A0009 OK FETCH completed." without any header in response to a header request for meeting reminder messages (with a "meeting.ics" attachment). fetchmail now treats these as transient errors.

Reported by Antoine Levitt. As a side effect of the fix, and in order to avoid a full rewrite, fetchmail will now CRLF-terminate the last line fetched through IMAP, even if it is originally not terminated by LF or CRLF. This bears no relevance if your messages end up in mbox, but adds line termination for storages (like Maildir) that do not require that the last line be LF- or CRLF-terminated. # CONTRIB/ addition * There is a patch against fetchnews's source, contrib/rawlog.patch, that can log (and hexdump non-printing characters) raw socket data to a file. It proved useful to debug Antoine's bug described above. fetchmail-6.3.20 (released 2011-06-06, 26005 LoC): # SECURITY BUG FIXES * CVE-2011-1947: STARTTLS: Fetchmail runs the IMAP STARTTLS or POP3 STLS negotiation with the set timeout (default five minutes) now. This was reported missing, with observed fetchmail freezes beyond a week, by Thomas Jarosch. SSL-wrapped connections were unaffected by this timeout, so users of older versions can force ssl-wrapped connections -- if supported by the server -- with the --ssl command line or ssl rcfile option. See fetchmail-SA-2011-01.txt for further details. # BUG FIXES * IMAP: Do not search for UNSEEN messages in ranges. Usually, there are very few new messages and most of the range searches result in nothing. Instead, split the long response to make the IMAP driver think that there are multiple lines of response. (Sunil Shetye) * Do not print "skipping message" for old messages even in verbose mode. If there are too many old messages, the logs just get filled without any real activity. (Sunil Shetye) (suggested by Yunfan Jiang) * Build: fetchmail now always uses its own MD5 implementation rather than trying to find a system library with matched header. The library and header variants found on systems are too diverse, and the code size saving is not worth any more wasted user or programmer time. # CHANGES * Call strlen() only once when removing CRLF from a line. (Sunil Shetye) * fetchmail sets Internet domain sockets to "keepalive" mode now. Note that there is no portable way to configure actual timeouts for this mode, and some systems only support a system-wide timeout setting. fetchmail does not attempt to tune the time spans of keepalive mode. # TRANSLATION UPDATES [cs] Chech (Petr Pisar) [nl] Dutch (Erwin Poeze) [fr] French (Frédéric Marchal) [de] German (Matthias Andree) [ja] Japanese (Takeshi Hamasaki) [pl] Polish (Jakub Bogusz) [sk] Slovak (Marcel Telka) fetchmail-6.3.19 (released 2010-12-10, 25945 LoC): # ERRATUM NOTICE ISSUED * fetchmail 6.3.18 contains several bug fixes that were considered sufficiently grave to warrant the issue of an erratum notice, fetchmail-EN-2010-03.txt. # BUG FIXES * When specifying multiple local multidrop lists, do not lose wildcard flag. (Affects "user foo is bar baz * is joe here") * In multidrop configurations, an asterisk can now appear anywhere in the list of local users, not just at the end. * In multidrop mode, header parsing is now more verbose in -vv mode, so that it becomes possible to see which header is used. * Make --antispam work from command line (these used to work in rcfiles). Reported by Kees Bakker, BerliOS Bug #17599. (Sunil Shetye) * Smoke test XHTML 1.1 validation, and if it fails, skip validating HTML documents. Skip validating Mailbox-Names-UTF7.html. Several systems have broken XHTML 1.1 DTD installations that jeopardize the build. Reported by Mihail Nechkin against FreeBSD port. Workaround for 6.3.18: build in a separate directory, i. e: mkdir build && cd build && ../configure --options-go-here * Send a NOOP only after a failed STARTTLS in IMAP. (Sunil Shetye) * Demote GSSAPI verbose/debug syslog to INFO severity. Requested by Carlos E. R. and Derek Simkowiak via the fetchmail-users@ mailing list. * Do STARTTLS/STLS negotiation in IMAP/POP3 if it is mandatory even if the server capabilities do not show support for upgradation to TLS. To use this, configure --sslproto tls1. (Sunil Shetye) * IMAP: Understand empty strings as FETCH response, seen on Yahoo. Reported by Yasin Malli to fetchmail-users@ 2010-12-10. Note that fetchmail continues to expect literals as FETCH response for now. # DOCUMENTATION * The manual page now links to IANA for GSSAPI service names. # TRANSLATION UPDATES [cs] Czech (Petr Pisar) [fr] French (Frédéric Marchal) [de] German [it] Italian (Vincenzo Campanella) [pl] Polish (Jakub Bogusz) fetchmail-6.3.18 (released 2010-10-09, 25936 LoC): # SECURITY IMPROVEMENTS TO DEFANG X.509 CERTIFICATE ABUSE * Fetchmail now only accepts wildcard certificate common names and subject alternative names if they start with "*.". Previous versions would accept wildcards even if no period followed immediately. * Fetchmail now disallows wildcards in certificates to match domain literals (such as 10.9.8.7), or wildcards in domain literals ("*.168.23.23"). The test is overly picky and triggers if the pattern (after skipping the initial wildcard "*") or domain consists solely of digits and dots, and thus matches more than needed. * Fetchmail now disallows wildcarding top-level domains. # CRITICAL BUG FIXES AND REGRESSION FIXES * Fetchmail 6.3.15, 6.3.16, and 6.3.17 would pick up libmd5 to obtain MD5* functions, as an effect of an undocumented Solaris MD5 fix. This caused all MD5-related functions to malfunction if, for instance, libmd5.so was installed on other operating systems as part of libwww on machines where long isn't 32-bits, i. e. usually on 64-bit computers. Fixes Gentoo Bug #319283, reported, including libwww hint, by Karl Hakimian. Side effect: fetchmail will now use -lmd on Solaris rather than -lmd5. * Fetchmail 6.3.17 warned about insecure SSL/TLS connections even if a matching --sslfingerprint was specified. This is an omission from an SSL usability change made in 6.3.17. Fixes Debian Bug#580796 reported by Roland Stigge. * Fetchmail will now apply timeouts to the authentication stage. This stage encompasses STARTTLS/STLS negotiation in IMAP/POP3. Reported missing by Thomas Jarosch. * Fetchmail now cancels GSSAPI authentication properly when encountering GSS errors, such as no or unsuitable credentials. It now sends an asterisk on a line by its own, as required in SASL. This fixes protocol synchronization issues that cause Authentication failures, often observed with kerberized MS Exchange servers. Fixes Debian Bug #568455 reported by Patrick Rynhart, and Alan Murrell, to the fetchmail-users list. Fix verified by Thomas Voigtmann and Patrick Rynhart. # BUG FIXES * Fetchmail will no longer print connection attempts and errors for one host in "silent" and "normal" logging modes, unless all connections fail. This should reduce irritation around refused-connection logging if services are only on an IPv4 socket if the host also supports IPv6. Often observed as connections refused to ::1/25 when the subsequent connection to 127.0.0.1/25 then - silently - succeeds. Fetchmail, unless in verbose mode, will collect all connect errors and only report them if all of them fail. * Fetchmail will not try GSSAPI authentication automatically, unless it has GSS credentials. However, if GSSAPI authentication is requested explicitly, fetchmail will always try it. * Fetchmail now parses response to "FETCH n:m RFC822.SIZE" and "FETCH n RFC822.HEADER" in a more flexible manner. (Sunil Shetye) * The manual page clearly states that --principal is for Kerberos 4 only, not for Kerberos 5 or GSSAPI. Found by Thomas Voigtmann. # CHANGES * When encountering incorrect headers, fetchmail will refer to the bad-header option in the manpage. Fixes BerliOS Bug #17272, change suggested by Björn Voigt. * Fetchmail now decodes and reports GSSAPI status codes upon errors. * Fetchmail now autoprobes NTLM also for POP3. * The Fetchmail FAQ has a new item #R15 on authentication failures. # INTERNAL CHANGES * The common NTLM authentication code was factored out from pop3.c and imap.c. # TRANSLATION UPDATES [zh_CN] Chinese/simplified (Ji Zheng-Yu) [cs] Czech (Petr Pisar) [nl] Dutch (Erwin Poeze) [fr] French (Frédéric Marchal) [de] German [it] Italian (Vincenzo Campanella) [ja] Japanese (Takeshi Hamasaki) [pl] Polish (Jakub Bogusz) [sk] Slovak (Marcel Telka) fetchmail-6.3.17 (released 2010-05-06, 25767 LoC): # SECURITY FIX * CVE-2010-1167: Fetchmail before release 6.3.17 did not properly sanitize external input (mail headers and UID). When a multi-character locale (such as UTF-8) was in use, this could cause memory exhaustion and thus a denial of service, because fetchmail's report.c functions assumed that non-success of [v]snprintf was due to insufficient buffer size allocation. It would then repeatedly reallocate a larger buffer and fail formatting again. See fetchmail-SA-2010-02.txt. # FEATURES * Fetchmail now supports a --sslcertfile option to specify a "CA bundle" file (a file that contains trusted CA certificates). Since these bundled CA files do not require c_rehash to be run, they are easier to use and immune to OpenSSL library updates that affect the hash function. * Fetchmail now supports a FETCHMAIL_INCLUDE_DEFAULT_X509_CA_CERTS environment variable to force loading the default SSL CA certificate locations even if --sslcertfile or --sslcertpath is used. If neither option is in effect, fetchmail loads the default locations. # REGRESSION FIX * Fix string handling in rcfile scanner, which caused fetchmail to misparse a run control file in certain circumstances. Fixes BerliOS bug #14257. Patch by Michael Banack. This fixes a regression introduced before 6.3.0. # BUG FIXES * Plug memory leak when using a "defaults" entry in the run control file. * Do not print SSL certificate mismatches unless verbose or --sslcertck is enabled. * Do not lose "set invisible" in fetchmailconf. (Michael Barnack) # CHANGES * Usability: SSL certificate chains are fully printed in -v -v mode, and there are now helpful pointers to --sslcertpath and c_rehash for "unable to get local issuer certificate" and self-signed certificates -- these usually hint to missing root signing CAs in the certs directory. * Several fixes for compiler (GCC, Intel C++, CLang) and autotools warnings * Memory allocation failures will now cause abnormal program abort (SIGABRT), no longer an exit with unspecified code. * Print a warning if certificate verification failed and the user did not specify --sslcertck. # DOCUMENTATION * Fix table of global option to read "set softbounce" where there used to be a 2nd copy of "set spambounce". Patch by Michael Banack, BerliOS Bug #17067. * In the --sslcertpath description, mention that OpenSSL upgrade (and a 0.9.X to 1.0.0 upgrade in particular) may require running c_rehash. # TRANSLATION UPDATES [zh_CN] Chinese/simplified (Ji Zheng-Yu) [cs] Czech (Petr Pisar) [nl] Dutch (Erwin Poeze) [fr] French (Frédéric Marchal) [de] German [id] Indonesian (Andhika Padmawan) [it] Italian (Vincenzo Campanella) [ja] Japanese (Takeshi Hamasaki) [pl] Polish (Jakub Bogusz) [sk] Slovak (Marcel Telka) [vi] Vietnamese (Clytie Siddall) fetchmail-6.3.16 (released 2010-04-06, 25574 LoC): # BUG FIX * Fix --interface option, broken in 6.3.15.

This specifies how messages with bad headers retrieved from the current server are to be treated. # BUG FIXES * In the rcfile, recognize "local" as abbreviation for "localdomains", as documented.

Reported by Frédéric Marchal. * Do not close stdout when using mda and "bsmtp -" at the same time. * Log operating system errors when BSMTP writes fail. * Fix verbose mode progress formatting regression from 6.3.10; SMTP trace lines were no longer on a line of their own. Reported by Melchior Franz. * Check seteuid() return value and abort running MDA if switch fails. * Set global flags in a consistent manner. Make --nosoftbounce and --nobounce work from command line (these used to work in rcfiles). Reported and fix confirmed working by N.J. Mann. (Sunil Shetye) * Properly import h_errno declarations, even on systems where h_errno isn't a macro. (Adds ./configure check, fixes Cygwin dllimport warnings.) # CHANGES * The repository has been converted and moved from the Subversion (SVN) format kindly hosted by Graham Wilson over the past years to Git format hosted on Gitorious.org. My deepest thanks to Graham Wilson for this service that kept us going when BerliOS's Subversion service was faulty in its early days. * This opportunity was used to convert BRANCH_6-2 and BRANCH_1-9-9 to GnuPG-signed tags, as a sign that these are now closed. * The outdated SVN trunk is now called "oldtrunk" in Git just to save the work for future reference. All development in the past few years was on BRANCH_6-3. * master was branched from BRANCH_6-3. BRANCH_6-3 is now obsolete (and in fact was also converted to a tag to record where the conversion from SVN to Git took place). * "make check" now skips HTML validation if xmllint or XHTML DTD are missing. # DOCUMENTATION * Web site and documentation were adjusted to reflect the SVN->Git move. * The fetchmail manual page is now much clearer on the user id switching (seteuid) when using --mda while running as the super user. # TRANSLATION UPDATES, by language name * [zh_CN] Chinese (Simplified), by Ji Zheng-Yu * [cs] Czech, by Petr Pisar * [nl] Dutch, by Erwin Poeze * [fr] French, by Frédéric Marchal * [de] German * [id] Indonesian, by Andhika Padmawan * [it] Italian, by Vincenzo Campanella * [ja] Japanese, by Takeshi Hamasaki * [pl] Polish, by Jakub Bogusz * [vi] Vietnamese, by Clytie Siddall fetchmail 6.3.14 (released 2010-02-05, 25487 LoC): # SECURITY FIXES * CVE-2010-0562: SSL/TLS certificate information is now also reported properly on computers that consider the "char" type signed. Fixes malloc() buffer overrun. Workaround for older versions: do not use verbose mode. See fetchmail-SA-2010-01.txt for details, including a minimal patch. # BUG FIXES * The IMAP client no longer skips messages from several IMAP servers including Dovecot if fetchmail's "idle" is in use. Causes were that fetchmail (a) ignored some untagged responses when it should not (b) relied on EXISTS messages in response to EXPUNGE, which aren't mandated by RFC-3501 (the IMAP standard) and aren't sent by Dovecot either. Fix by Sunil Shetye (the fix also consolidates IMAP response handling, improving overall robustness of the IMAP client), bug report and testing by Matt Doran, with further hints from Timo Sirainen. * The SMTP client now recovers from errors (such as servers dropping the connection after errors) when sending an RSET command. Fix by Sunil Shetye. Report by James Moe. * The IMAP client now uses "SEARCH UNSEEN" rather than "SEARCH UNSEEN NOT DELETED" again on IMAP2, to fix a regression in fetchmail 6.2.5 reported by Will Stringer in June 2004. (Sunil Shetye) * The IMAP client now uses "SEARCH UNSEEN UNDELETED" on IMAP4 and IMAP4r1 servers (Sunil Shetye). * Workaround: The IMAP client now falls back to "FETCH n:m FLAGS" if the server does not support "SEARCH". (Sunil Shetye) * The IMAP client now requests message numbers in batches of 1,000 to avoid problems if there are more than 1860 unseen messages. (Sunil Shetye) Note that this wasn't security relevant because fetchmail would only read up to the maximum buffer size and leave the remainder of the string unread, going out of synch afterwards. * Stricter validation of IMAP responses containing byte or message counts. # CHANGES * Only include gssapi.h if we're not including gssapi/gssapi.h, to fix a FreeBSD compiler warning about gssapi.h being obsolete. # DOCUMENTATION * The README.SSL document was revised for grammar, spelling, and clarity.

Workaround for older versions: run in verbose mode. Patch courtesy of Thomas Heinz, fixes Gentoo Bug #280760. This regression affected only the 6.3.11 release, but not the patch that was part of the security announcement fetchmail-SA-2009-01. # BUG FIXES * Fix error reporting for GSSAPI on Heimdal (h5l) Kerberos. * Look for MD5_Init in libcrypto rather than libssl, fixes Gentoo Kerberos builds; fixes upstream parts of Gentoo Bugs #231400 and #185652, and fixes BerliOS Bug #16134. * Report multiline SMTP errors properly, reported by Earl Chew; fixes Debian Bug #529899, reported by Akihiro Terasaki. Note: This fix introduced a regression, fixed in 6.3.13. * Replace control characters in SMTP replies by '?'. * Fetchmailconf: Fix descriptions for smtpaddress and smtpname options; smtpaddress is for RCPT TO, not MAIL FROM.

These fields use opaque strings with a separate length field, so that the NUL character isn't a special character inside the certificate. Fetchmail, being written in the C language, used to treat these strings as C strings nonetheless, so that the domain comparison would end at the first embedded NUL character, rather than at the real end of the string. Fetchmail will now abort certificate verification as failed if NULs are encountered inside either of these fields regardless of their position, and drop the connection even if --sslcertck is not used, because NUL is not a valid character in legitimate DNS names. See fetchmail-SA-2009-01.txt for details, including a minimal patch. # BUGFIXES * Remove the spurious message "message delimiter found while scanning headers". RFC-5322 syntax states that the delimiter is part of the body, and the body is optional. * Convert all non-printable characters in certificate Subject/Issuer Common Name or Subject Alternative Name fields to ANSI-C hex escapes (\xnn, where nn are hex digits). Note that this change introduces a regression, fixed in 6.3.12. See the 6.3.12 documentation above for details and a workaround. # TRANSLATION UPDATES AND ADDITIONS (ordered by language name): * [zh_CN] Chinese/Simplified (Ji ZhengYu) * [es] Spanish/Castilian (Francisco Molinero) fetchmail 6.3.10 (released 2009-07-02): # INCOMPATIBLE BUGFIXES AND CHANGES * Fetchmail no longer drops permanently undelivered messages by default, to match historic documentation. It does this by adding a new "softbounce" option, see below. Fixes Debian Bug#471283, demotes Debian Bug#494418 to wishlist. * There is a new "softbounce" global option that prevents the deletion of messages that have not been forwarded. It defaults to "true" for fetchmail 6.3.X in order to match historic documentation. This may change its default in the next major release. # BUGFIXES * Fix misuse of canonical autoconf target as _TARGET when it should have been _HOST. Report and patch courtesy of Diego E. "Flameeyes" Pettenò. Details: http://blog.flameeyes.eu/2009/01/01/the-canonical-target * Do not lose PS_MAXFETCH (13) exit status when hitting maxpoll. Reported by Michelle Konzack, Debian Bug#508667. * Do not overlap source and destination fields in snprintf() in interface.c. Courtesy of Nico Golde, Debian. * When a pre- or post-connect command fails, now report the exit status or termination signal properly through sys/wait.h macros. * When acquiring a body, understand NIL ("no such data item"), as returned by some MS Exchange versions. Fixes BerliOS Bug #11980 by KB Sriram. * Make progress tickers (-v/--showdots) consistent, and update documentation accordingly ("." for each 1024 octets read, "#" for a header written, and "*" for each body line written.) The conditions under which these had been printed were inconsistent, illogical, and documentation hadn't matched real behaviour for long. * For NTLM authentication, use dynamically allocated buffers. Fixes Debian Bug#449179, reported by Stepan Golosunov. * Non-delivery notice ("bounce mail") now mentions the original reason again, before the address list. This fixes a regression introduced in 6.3.0. * Several compiler warnings were fixed. * The minimum recommended SMTP (RFC-5321) timeouts are enforced to leave sufficient time for the listener to respond. Some synchronous listeners, particularly when used with spam filtering and other policy enforcement services, take extended amounts of time to process messages after the sender, recipient, or data block and EOM line. This can cause fetchmail to not wait long enough for the "250 Ok" and make fetchmail believe the message wasn't properly delivered when in fact it was; fetchmail would then retry the download next time and never make progress. Fixes Berlios Bug #10972, reported by Viktor Binzberger. * The ESMTP/LMTP client will now apply an application-specific timeout while waiting for the EHLO/LHLO response, rather than wait for the server or TCP connection timeout. * Treat 530 errors as temporary, so as not to delete messages on configuration errors. Partially taken from Petr Cerny's patch in Novell Bugzilla #246829. The 501 part of said patch was not added, as the maintainer is not convinced 501 is a temporary condition, and softbounce takes care of this anyways. # CHANGES * Make the comparison of the SSL fingerprints case insensitive, to ease its use. Suggested by Daniel Richard G. * Proper precedence ordering for the syslog and logfile options. If the logfile option is effective (i. e. we're in daemon mode and nodetach isn't used), reset the syslog option. If logfile is ineffective (we're not in daemon mode, or nodetach is set), syslog takes precedence. * The sleeping at/awakened at messages appear in logfiles and syslog only if verbose mode is enabled. On the console, they will still appear without verbose mode. Fixes Debian Bug#282259. * fetchmail only requests IPv6 addresses via name service if at least one is configured on the local host, likewise for IPv4. (AI_ADDRCONFIG flag to getaddrinfo()) Extended version of Redhat's patch. * If the server name contains "yahoo.com", offers the "ID" capability, and we're polling via IMAP, send an ID ("guid" "1") transaction first, ignoring its result. This appears needed to be able to log into Yahoo's Zimbra servers, but there are open issues (such as being only able to download one message and server certificate mismatches). # CHANGES TO CONTRIB * Fix bashism in contrib/fetchsetup. Fixes Debian Bug#530081. # DOCUMENTATION * Some parts of the the manual page were revised for clarity, accuracy, and updated recommendations (particularly SSL/TLS) and formatting conventions from man-pages(7). * The README and README.SSL documents were updated. * A document, README.SSL-SERVER, was added to describe server-side requirements for proper SSL and/or TLS service offerings. These are not specific to fetchmail. * Documentation on how to make "NOMAIL" (exit code 1) not treated an error has been added to the EXIT CODES section of the manpage and to the FAQ as item C8. The suggested solution uses a tiny POSIX shell script fragment.

Report & fix by Earl Chew. Note while this is theoretically a remote denial of service attack vector, fetchmail by default talks SMTP to the localhost, so the overall risk is rather low. This bug was apparently introduced on 1998-11-27 when the bouncemail facility was modularized. The bug then made its appearance in fetchmail release 4.6.8. See also fetchmail-SA-2007-02.txt. * CVE-2008-2711: Denial of service: When fetchmail logs data blobs (for instance, a To: header in -v -v verbose mode) in excess of 2048 bytes, it will crash, because it hands an uninitialized argument pointer (not the format string though) to vsnprintf and reads a random memory location (it calls va_arg() too often without resetting it with va_start()). Based on a patch (BerliOS patch #2492) by Petr Uzel, fixes Novell Bug #354291. Note 6.3.9-rc1 did not completely fix this issue, so it was redrawn a few hours after its release. See also fetchmail-SA-2008-01.txt. * When expunging, mark the right messages as seen to avoid message loss in "keep flush" configurations. Workaround for previous versions: "expunge 0". Report and patch by Alexander Cherepanov - thanks a lot, Berlios Bug #11797, "imap_mark_seen doesn't consider expunged messages". * SSL fix: close memory leak when SSL connection fails; fetchmail used to forget calling SSL_free() on the SSL context, leaking in excess of 500 kB RAM on a x86_64 system per failed SSL connection attempt. Bug reported and patch provided by Seiichi Ikarashi, Fujitsu. # BUG FIXES: * The configure script will additionally check for 'dn_skipname', to fix build failures with µClibc. The new check still recognizes the resolver libraries on Ubuntu 7.04, openSUSE 10.2, Solaris 8, NetBSD 4.0_BETA2 and FreeBSD 6.2. Fixes Gentoo bug #134187. NOTE: this is a bit of a hack, since we twist the HAVE_RES_SEARCH result, but res_search() and dn_skipname() are only used together and scheduled for removal in future versions, so this is probably fine. * No longer complain about invalid sslproto "" when POP3 CAPA probe fails. Fixes Debian Bug#421446 (Holger Leskien), Novell Bug #247233 (Jon Nelson), Red Hat Bug#503881. Thanks to Matthias Strauß for a configuration to reproduce the issue. * Allow .fetchmailrc and .fetchids to be symlinks, as the manpage does not document they aren't allowed - fixes Debian Bug #452907 (Roger Leigh). TOCTOU race persists. * fetchmailconf quotes mailbox (folder) names when writing the configuration. Fixes BerliOS Bug #13207 (reported + fix suggested by Terry Brown). * Only print "Deleting fetchids file" if there actually is one. Fixes Debian Bug#374514, reported by Dan Jacobson. * SSL fix: check and report if SSL_set_fd fails. # CHANGES: * autoconf 2.60 is now required to build fetchmail; it uses AC_USE_SYSTEM_EXTENSIONS to replace AC_AIX, AC_MINIX, and the like. * Removed dead FETCHMAIL_DEBUG code from fetchmail.h that was disabled by default with no switches in configure to enable it. However, the macro would have been prone to a symlink attack. Found by Nico Golde. * Removed dead FORCE_STUFFING code from socket.c that was disabled by default with no switches in configure to enable it. * Include the typedef for int16 in the #ifndef _AIX in smbencrypt.c (Peter O'Gorman) * Correct check for u_int32_t in configure.ac (seems to be typedef'ed in namser.h on some platforms.) (Peter O'Gorman) * In configure.ac change all CPFLAGS to CPPFLAGS, CEFLAGS to CFLAGS and LDEFLAGS to LDFLAGS otherwise the results of some tests (additional -L and -I flags) do not get used for later tests causing incorrect configure results. Makefile.am was also changed to reflect this. (Peter O'Gorman) * m4/gethostbyname_r.m4 does AC_TRY_COMPILE, which unfortunately can pass even if there is no gethostbyname_r. Changed to AC_TRY_LINK. (Peter O'Gorman) * Revise getnameinfo check to ensure NULL is defined and the result is properly evaluated, to avoid bogus results on for instance FreeBSD and redefinitions of NI_* at compile time. (Matthias Andree). * __attribute__ ((unused)) is a gccism, removed from libesmtp/gethostbyname.c. (Peter O'Gorman) * In KAME/getnameinfo.c it's best to use the correct argument to inet_ntoa. (Peter O'Gorman) * In verbose mode, log if --check mode is enabled. * Add sslcommonname option (rcfile and commandline) as a way to work around misconfigured upstream SSL servers that use the wrong certificate name. It specifies which CommonName fetchmail expects and logs. (Daniel Richard G.) * Changed CRLF to LF line endings in contrib/delete-later (reporter: Petr Uzel) * SSL change: enable all workarounds with SSL_CTX_set_options(ctx,SSL_OP_ALL) * All translations have been re-enabled, in an attempt to rekindle translator or user interest. # DOCUMENTATION: * Add fetchmail-SA-2007-02.txt and fetchmail-SA-2008-01.txt. * Re-add two lines to the manual page that had accidentally become comments to nroff. One was part of the --sslproto documentation, and one in the "Awakening the background daemon" section. * The manual page no longer asserts that .fetchids were for exclusive POP3 use, since it is planned to use the file with IMAP4 later. * Add grammar fixes from Dan Jacobson to fetchmail.man. Debian Bug #461642. * The manual page now mentions that user descriptions need to come before user options. Reported by Francensco Pontortì, to fix Debian Bug #467010. * The manual page no longer hints that multi-user declarations per server were only useful in daemon mode running as root, to avoid hinting people to doing that. * Several manual page rcfile examples now include "ssl". * The manual page hints that option arguments beginning with numbers can be enclosed in quotes. * The manual page now mentions that the --logfile must already exist before fetchmail is run. * The FAQ now recommends (#I9) not to use Google Mail for their disregard to the protocols they claim to support. * Documentation and program output now /consistently/ claim that the rcfile must not have more than 0700 (u=rwx,g=,o=) permissions, but fetchmail will still silently accept additional g=x permissions for compatibility with previous 6.2.X and 6.3.X versions. Inconsistency (program 0710, manpage 0600) reported by Petr Uzel. * The --logfile documentation is now clearer about requiring detached daemon mode. # TRANSLATION UPDATES AND ADDITIONS (ordered by language name): * [sq] Albanian (Besnik Bleta) * [zh_CN] Chinese, simplified (Ji Zheng-Yu) * [cs] Czech (Petr Pisar) * [da] Danish (Byrial Ole Jensen) - outdated, but newer than in 6.3.8 * [nl] Dutch (Tony Vroon, Benno Schulenberg) * [en_GB] English, British * [fi] Finnish (Lauri Nurmi) * [de] German * [id] Indonesian (Andhika Padmawan) * [ja] Japanese (Takeshi Hamasaki) * [pl] Polish (Jakub Bogusz) * [ru] Russian (Pavel Maryanov) * [es] Spanish (Javier Fernández-Sanguino Peña, Matthias Andree) * [tr] Turkish (Engin Gündüz) - outdated, but newer than in 6.3.8 * [vi] Vietnamese (Clytie Siddall) fetchmail 6.3.8 (released 2007-04-06): # SECURITY STRENGTHENING: * Make the APOP challenge parser more distrustful and have it reject challenges that do not conform to RFC-822 msg-id format, in the hope to make mounting man-in-the-middle attacks (MITM) against APOP a bit more difficult. (CVE-2007-1558, reported by Gaëtan Leurent, published 2007-04-02 on Bugtraq) APOP is claimed insecure by Gaëtan Leurent for MITM scenarios for typical setups: based on MD5 collisions, it is purportedly possible to recover the first three characters of the shared secret (password), which would then make recovery of the shared secret a matter of hours or minutes; this would then enable the attacker to impersonate the client vis-à-vis the server.

Reported by Uli Zappe. fetchmail 6.3.6 (released 2007-01-04): # SECURITY FIXES: * CVE-2006-5867, fetchmail-SA-2006-02.txt: Password disclosure vulnerability fixed. This has several aspects: - Fetchmail now implies sslproto 'tls1' if the sslfingerprint or sslcertck options are used and the ssl option is not used, in order to be sure that fetchmail gets a certificate from the mail server. - Fetchmail breaks the connection if the TLS negotiation (or verification, if requested) fails with sslproto 'tls1', sslfingerprint or sslcheck enabled. - POP3 connections now use STLS reliably. They used to ignore STLS altogether for serveral values of the "auth" option, when fetchmail forget to probe server capabilities - see fetchmail-SA-2006-02.txt for details. - POP3 connections will no longer fall back USER/PASS authentication if strong challenge-response authenticators such as CRAM-MD5 are configured but the server does not advertise these in its CAPA response. - POP2 is obsolete and does not support STLS or anything beyond password-based authentication. The attempt to use STLS or strong authenticators now causes connection abort. Configurations using both ssl and sslcertck however have been semi-safe in that they would send the password in the clear. The USER/PASS fallback problem however applies to these too, so that the password was only safe on trustworthy servers. * CVE-2006-5974, fetchmail-SA-2006-03.txt: Repairs a regression in 6.3.5 that crashes fetchmail when a message with invalid headers is found while fetchmail's mda option is in use. BerliOS bugs #9364, #9412, #9449. Stack backtrace provided by Neil Hoggarth - thanks. # REGRESSION FIXES (recently introduced bugs) * Repair --logfile, broken in 6.3.5. BerliOS Bug #9059, reported by Brian Harring. * Repair --user, broken in 6.3.5 (as a side effect of the authenticate external patch): using SSL certificate/key authentication overrode the --user option. Now the latter takes precedence, and only defaults to the certificate's common name. Debian Bug #400950, reported by Jorgen Schaefer . # BUG FIXES (long-standing bugs): * RPOP: used to log the password locally rather than an asterisk as the other protocols do. The password is now shrouded in the local logs. * POP3: Probes capabilities now when Kerberos V5 is enabled, so that we can actually detect if the server supports it. * Robustness: If a stale lockfile cannot be deleted, truncate it so that fetchmail doesn't later believe itself to be running if the PID is recycled by a non-fetchmail process. * DNS: Detect /etc/resolv.conf changes: On systems that have res_search(), assume we also have res_init() and call it (suggested by Ulrich Drepper, glibc bug #3675) in order to make libc or libresolv reread the resolver configuration at the beginning of a poll cycle. This is important when fetchmail is in daemon mode and /etc/resolv.conf is changed later by dhcpcd, dhclient, pppd, openvpn or other ip-up/ipchange scripts. Should fix Debian Bug#389270, Bug#391698. * Robustness: Fix crash on systems that do not provide strdup(), the crash happens only in out-of-memory conditions when fetchmail cannot proceed anyways. Patch by Andreas Krennmair. * Robustness: When HOME and FETCHMAILHOME are unset, be sure to copy user database information, so it is not trashed later. Patch by Jim Correia. # CHANGES: * Workaround: Improve handling of IMAP IDLE, some servers do not reset their time counters after sending information asynchronously. Patch by Sunil Shetye, after report from Andrew Baumann. * Usability: When requesting Kerberos or GSSAPI, complain and exit with syntax error if any of these requested features has not been compiled in. This is to fail early and with precise error message. Reported by Isaac Wilcox. * --version will now add +KRB4 or +KRB5 if Kerberos v4 or v5, respectively, have been compiled in. Reported missing by Isaac Wilcox. # TRANSLATIONS: * New en_GB (British English) translation by David Lodge. * Update Japanese (Takeshi Hamasaki), Polish (Jakub Bogusz), Russian (Pavel Maryanov) and Vietnamese (Clytie Siddall) translations. ! Note that not all these translations are complete -- this isn't the translators' fault though, but due to delays at the BerliOS hosting site and the translation project handlers. You may see a few untranslated messages. # DOCUMENTATION: * Dropped exit status 15 from manual page, it's not used by fetchmail. Reported by Isaac Wilcox. * Documented exit codes 24 - 29 as internal. fetchmail 6.3.5 (released 2006-10-09): # BUG FIXES: * For protocols such as IMAP that are not delimited by "." lines, truncate the input buffer when the message has been completely read, to avoid taking trailing garbage into the message if the terminal CRLF is missing. Fixes Debian Bug#312415. (Patch suggested by Mike Jones, Manchester Univ.). * When using NTLM authentication, use regular IMAP response code handler after completing NTLM handshake, for robustness and consistency. (Taken from the NetBSD portable packages collection, patch-ac.) * Support Kerberos installations where krb5.h and perhaps roken.h are in .../include/krb5. Taken from NetBSD portable packages collection patch-ae. * On NetBSD, link against -lroken -lcom_err if --with-kerberos is enabled. * Drop #include from Kerberos 5 header file, fixes compile error on SUSE Linux 10.0. * Fix des_pcbc_encrypt compile warnings in kerberos.c line 246. * If krb5-config provides gssapi library information, use that rather than guessing. * Improve --with-gssapi auto detection for /usr-based GSSAPI installs. * Fix --with-gssapi builds for NetBSD 3.0. * Improve KAME/getnameinfo.c portability to Linux libc5 systems. Based on a patch by Dan Fandrich. * Provide INET6 to KAME/getnameinfo.c (only useful on IPv6-enabled systems that lack getnameinfo, and there only visible in some Received: headers). Found by Dan Fandrich. * POP3: some UID flags may not be set properly on UIDL lists. (Sunil Shetye) * Make IMAP4 IDLE work on servers that do not update RECENT counts. Reported by Lars Tewes. * IMAP4 patch by Sunil Shetye: - do not depend on server updating RECENT counts at all - also enter IDLE loop when messages are present on the server. * Fix --flush description in the manual page, fetchmail does not mark messages seen unless it has successfully delivered them. Suggested by Frederic Marchal. * Fetchmail no longer attempts to stat the "-" file in daemon mode -- this is a special name to read the RC file from stdin, and cannot always be re-read anyways. BerliOS bug #7858. * When looking up ports for a service, the lookup succeeds and the returned address family isn't IPv4 or IPv6, properly free the allocated memory from the service lookup. Found by Uli Zappe. * When looking up ports for a service, only look up TCP ports. * Avoid compiling empty files, to avoid diagnostics from strict compilers. * If the lockfile ends before the process ID, treat it as stale and unlink it. Reported by Justin Pryzby, Debian Bug #376603. * SIGHUP wake-up behavior was broken since 5.9.13's Cygwin changes, in that for non-root users, SIGHUP would abort the first poll and subsequently interfere with new polls, and SIGHUP would be ignored for root users. SIGHUP now matches documented behavior. SIGUSR1 has always been a wakeup signal for both root (undocumented) and non-root users. See also the deprecation warning above. * Track getaddrinfo() results to properly free them after timeouts and make sure that getaddrinfo() isn't interrupted by a timeout (which breaks on MacOS X), reported by Uli Zappe. This should fix Debian Bug#294547 and Bug#377135. * --logfile is now handled more carefully, errors opening the logfile are now reported to the TTY where fetchmail was started from. * fetchmail now complains and aborts when it cannot properly daemonize itself. * fix compilation on systems that don't know struct addrinfo (Solaris 2.6). * ignore SIGPIPE signals and rely on functions to return EPIPE instead. This is necessary because the former longjmp() from the signal handler is unsafe and makes the whole fetchmail behavior undefined after the event. * Avoid crash in env.c/host_fqdn if we cannot canonicalize our own hostname. Reported by Alexander Holler. * SSL fix by Miloslav Trmac (Red Hat): free the SSL contexts after the connection, to avoid from growing SSL certpaths without bounds, avoid using SSL contexts for unrelated connections, and to fix Red Hat Bug #206346. # CHANGES: * Rename all fetchmail-internal lock_* functions to fm_lock_*. Obsoletes NetBSD portable packages collection patch-ah, patch-ai and patch-aj. * Configure prints a warning (but proceeds) if Kerberos IV support is enabled. * In verbose mode, log every IP fetchmail tries to connect to, to avoid misleading the user. Suppress EAFNOSUPPORT errors from socket() call, too. Fixes Debian Bug #361825, reported by Daniel Baur. * In idle mode, fetchmail complains about the fetchall option. * When a connection fails, log not only the IP address, but also host and service name and the port number. Log the latter when trying to connect in verbose mode, too. * Keep syslog output at one line per message (this works if no errors occur). * Fetchmail in verbose mode now logs if it opportunistically upgrades a POP3 or IMAP connection to TLS security with STLS/STARTTLS. * fetchmail now supports foo@example.org=bar user mappings for multidrop boxes. * switch setjmp/longjmp to sigsetjmp/siglongjmp * IMAP now supports the EXTERNAL authentication method, courtesy of Götz 'nimrill' Babin-Ebell, BerliOS patch #1095 with minor changes. Note that this change causes --sslcert to override --user. * The sslproto keywords are now case insensitive, courtesy of Götz 'nimrill' Babin-Ebell, BerliOS patch #1095. * When going to sleep, log for how long. Suggested by Claudia Ludwig. * When the server name cannot be canonicalized, log the gai_strerror value. # TRANSLATION UPDATES: * Catalan/ca (Ernest Adrogué Calveras), Japanese/ja (Takeshi Hamasaki) - also made gettext 0.15 ready, Polish/pl (Jakub Bogusz), Russian/ru (Pavel Maryanov), Spanish/es (Héctor García Álvarez), Vietnamese/vi (Clytie Siddall) # CONTRIBUTED SCRIPTS: * PopDel.py was revised by Joshua Crawford to display the From: address and list every email, even if it has no Subject: header; and not delete the wrong message in the presence of mail without Subject: headers. fetchmail 6.3.4 (released 2006-04-14): # BUG FIXES: * configure: detect res_* functions properly with newer glibc ABIs. Patch by Miloslav Trmac. * tracepolls: add folder information if available. Reported by Terry Brown. * lexer: add %option noyywrap to avoid link errors about missing yywrap(). * a few more type fixes for report/snprintf, patch by Miloslav Trmac. * bouncing: fetchmail would still send "General SMTP/ESMTP error." bounces in spite of "no bouncemail" configuration. * SSL/TLS: if, for a certain server, an sslfingerprint is specified and sslcertck is NOT set, suppress printing SSL certificate mismatch errors. (Reported by Hannes Erven.) * SSL/TLS: always print if the sslfingerprint mismatches, even in silent mode. (This is for consistency with certificate verification errors.) # TRANSLATION UPDATES: * German/de (Matthias Andree), French/fr (Matthias Andree), Spanish/es (Héctor García), Polish/pl (Jakub Bogusz), Japanese/ja (Takeshi Hamasaki) * New Vietnamese/vi translation (Clytie Siddall). * Updated French descriptions for the .spec file (Stéphane Schildknecht, Luc Pionchon, Matthias Andree). # CHANGES: * pidfile: there is a new command-line (--pidfile PATH) and global option for the rcfile (set pidfile [=] "/path/to/pidfile") option to allow overriding the default location of the PID file. Requested by Héctor García, Debian maintainer. * specgen.sh: Converted to UTF-8 to support translated texts better. fetchmail 6.3.3 (released 2006-03-30): # BUG FIXES: * SEGFAULT: Do not attempt to overwrite the netrc password if none has been specified. This fixes a segmentation fault bug introduced into 6.3.2. Fixes BerliOS bug #6234. BerliOS patch #804 by Craig Leres. The patch, as accepted into fetchmail, was available separately from * SEGFAULT: Work around C libraries that return a NULL in getaddrinfo()'s ai_canonname record, to avoid a segfault. Affects for instance FreeBSD 4.10, 4.11 and 5.3 when dotted quads are given as server names. Analysis and fix by Vladimir Olegovich Ravodin (Владимир Олегович Раводин). * IMAP: fix hangs in NOOP-based IDLE emulation. Reported by Casper Gripenberg and Brendan Lynch, fix by Sunil Shetye (his patch was merged) and Brendan Lynch. * IMAP: Handle other clients concurrently accessing IMAP mailboxes better. Fetchmail quits the poll if the EXPUNGE count does not match expectations, and servers not updating RECENT counts after EXPUNGE are handled in a better way. (Patch by Sunil Shetye.) * IMAP: Stop sending EXPUNGE after NOOP-idling (patch by Sunil Shetye). * POP3: fetchmail can now use UIDL in fetchall keep mode, to avoid re-fetching the same messages again when the fetchall keyword is removed. Patch by Sunil Shetye. For details, please see * LMTP: fix bug in LMTP port validation (patch by Miloslav Trmac). * SDPS: fetchmail no longer replaces the local user ID for an empty envelope sender when using the proprietary SDPS extension for POP3. Fixes Debian Bug#353575, reported by Roger Lynn. * SDPS: Warn and disable SDPS if POP3 is disabled to avoid compilation errors. * fetchmail no longer prints empty lines in verbose mode when using syslog. * fetchmail no longer prints UID lists in verbose mode when using syslog. * ./configure --quiet is now quieter (no SSL and fallback-related output). * Miloslav Trmac's patch (with minor changes) to fix char * sign consistency, unused arguments and variables. * More signedness, unused argument/variable and other warning fixes. # CHANGES: * --idle can now be specified on the command line, too. * --fetchall is now supported on the command-line. * POP3: Lower default fastuidl span to 4 (i. e. every 4th run fetches the whole UIDL list), patch by Sunil Shetye. # DOCUMENTATION: * "ssl" is a user option rather than a server option. Patch by Nico Golde. Fixes Debian Bug#354661, reported by Keith Hellman. * The manual page now suggests "--" before the addresses in the sendmail MDA example, for safety. * The FAQ item X9, Domino IMAP omits Content-Transfer-Encoding header, was added. Information provided by Anthony Kim on the fetchmail-friends list in March 2006. * Credit Chris Boyle with the NOOP emulation code for IDLE in fetchmail 6.2.4. Eric forgot to credit Chris, thanks to Sunil Shetye for providing these links: http://lists.ccil.org/pipermail/fetchmail-friends/2003-July/007705.html http://lists.ccil.org/pipermail/fetchmail-friends/2003-July/007713.html * Added a section about RETR vs. TOP to the manual page. * Changed section/subsection levels in some areas. fetchmail 6.3.2 (released 2006-01-22): Unless otherwise noted, changes to this release were made by Matthias Andree. # SECURITY FIX IN THIS RELEASE * CVE-2006-0321: Fix segfault or bus error after bouncing a message. This bug was introduced into 6.3.0 when removing alloca(); it caused fetchmail to free random memory. Reported by Nathaniel W. Turner, Debian Bug#348747. See fetchmail-SA-2006-01.txt # INCOMPATIBLE CHANGE: * Automatically disable the POP3 TOP command if the greeting string contains "Maillennium POP3/PROXY server", which is used by comcast and known to truncate messages after 80 kByte. Fall back to RETR, and complain if we had used TOP otherwise (the warning is printed only once per server in daemon mode). Suggested by Ed Wilts. *Note* that this means messages are marked read on these servers, which is a deviation from how 6.3.1 behaved, but we have no alternative, comcast haven't fixed this bug in years. Preventing the loss of the remainder of the message justifies this incompatible fix. * fetchmail, since 6.3.0, requires write permission to the directory holding the idfile. See the amendment in the 6.3.0 MAJOR INCOMPATIBLE CHANGES section below for details. The manual page was updated. # CHANGES RELEVANT TO PACKAGERS: * The outdated BUGS document was removed from the distribution. * Added fetchmail-SA-2006-01.txt to the distribution. # BUG FIXES: * SMTP/LMTP cleanup to fix these two bugs: - switch back to SMTP after having tried LMTP hosts (multiple smtphost hosts) - switch back to LMTP after sending a bounce. The patch removes the global state variable that was the root of this problem. Patch by Sunil Shetye. (MA) * Don't complain about fetchall keep in --configdump mode. Bug introduced in 6.3.0. * fetchmailconf.py: Fix novice help for Poll interval and fetchall. Reported by Justin Pryzby, Debian Bug #344978. * Some verbose output disappeared in debug mode. Adding further -v options would alternate between verbose and debug mode. debug mode now comprises all verbose output, and adding more -v options does not switch back from debug to verbose mode. * fetchmail.man: Fix accented characters in Héctor García's name. Merged from downstream debian/patches/01_man_page.dpatch. * Add missing --help text for "--sslcertck" option. * fetchmailconf.py: Accept --help and --version. * fetchmail --version now prints the copyright notice. * don't complain about READ-ONLY IMAP folders in --fetchall --keep mode. Reported Alexander Zangerl, Debian Bug#348964. * the RPM .spec file now generates a -debuginfo package on newer RPM versions. fetchmail 6.3.1 (released 2005-12-19): # SECURITY FIX IN THIS RELEASE * CVE-2005-4348 Fix segmentation fault (null pointer dereference) in multidrop mode with headerless email. See fetchmail-SA-2005-03.txt. Reported by Daniel Drake, patch by Sunil Shetye. (MA) # OTHER BUG FIXES, DOCUMENTATION AND TRANSLATION UPDATES * Fix broken default port in POP2. Patch by Stanislav Brabec, SUSE [CZ]. (MA) * Fix manual page, some lines starting with ' were escaped by \&. Reported by Simon Barner. (MA) * Ship with gettext-0.14.3 again, as 6.2.9-rc10 did. Found by Sunil Shetye. (MA) * Actually set default SSL certificate path if --sslcertpath is unset. Reported by Heino Tiedemann and Rob MacGregor. (MA) * Remove bogus Netscape IMAP4rev1 Service >= 3.6 warning about BODY[TEXT] that we are not using. Patch by Sunil Shetye. (MA) * Plug potential memory and socket leak when polling multiple folders or when the upstream sends bogus message sizes. Patch by Sunil Shetye. (MA) * Update Catalan translation, by Ernest Adrogué Calveras. (MA) * Fix segfault (null pointer dereference) on some operating systems with fetchmail's obsolete DNS MX/host alias lookups in multidrop mode. Patch by Dr.-Ing. Andreas Haakh. (MA) * Close SMTP sockets early, to reduce resource usage, trigger earlier delivery with some MTAs and avoid SIGPIPE (SIG 13) when the SMTP listener gets bored and drops the connection after timeout. Patch by Sunil Shetye. (MA) * Don't treat hitting a fetch limit as error. Patch by Sunil Shetye. (MA) * Fix negative "messages left on server" on idle/repoll with fetchlimit. Patch by Sunil Shetye. (MA) * Properly track logout stage. Patch by Sunil Shetye. (MA) * Preserve error conditions across postconnect script. Sunil Shetye. (MA) * Do not trash destination domain if multiple messages are forwarded into the same SMTP/LMTP connection. Reported by Joachim Feise, Berlios Bug #5849. (MA) * Manual page: Add "-md5" to "openssl x509" example in --sslfingerprint documentation, since OpenSSL 0.9.8 changed the default to SHA1. Suggested by Jason White. (MA) * Cope with servers that return UID information in response to non-UID RFC822.{SIZE|HEADER} requests. Reported by Jason White. Patch suggestion by by Sunil Shetye, simplified by MA. fetchmail 6.3.0 (released 2005-11-30): # SECURITY FIXES IN THIS RELEASE * CVE-2005-2335: The POP3 UIDL code doesn't sufficiently validate/truncate the input length, so a (malicious or compromised) server that sends UIDs longer than 128 bytes can corrupt fetchmail's stack and crash fetchmail. This vulnerability is remotely exploitable to inject code run in a root shell. Edward J. Shornock, Ludwig Nussel. fetchmail-SA-2005-01.txt * CVE-2005-3088: fetchmailconf now changes the output file to mode 0600 BEFORE writing to it, so there is no window where passwords could be read by the world. Matthias Andree. fetchmail-SA-2005-02.txt # MAJOR INCOMPATIBLE CHANGES * Remove support for --netsec/-T options, the required inet6_apps library is no longer available. http://www.inner.net/pub/ipv6/ states, as of 2005-07-03: "/pub/ipv6 Our IPv6 software is now long defunct. Please find a more modern source." I haven't been able to find a more modern source. Matthias Andree * Operating systems that do not conform to the Single Unix Specification v2 (1997) or v3 (2001, aka IEEE Std 1003.1-2001) are no longer supported. They may continue to work and non-intrusive patches to support them may be accepted. Matthias Andree * The default for --smtphost is now always "localhost" regardless of authentication types and protocols, so as to simplify configurations for workstations where the SMTP daemon only listens on the loopback interface. Sunil Shetye & Matthias Andree Amendment, 2006-01-04: * fetchmail's idfile (.fetchids) is no longer written directly, but the ids are written to a temporary file which is renamed into place after being written completely. This is to avoid writing incomplete idfiles when running out of space, which would cause excessive duplicate refetches of messages, this might make matters even worse. This means that fetchmail requires write permission on the directory holding the idfile. This will usually affect system-global daemons only, for instance, Debian. Found by Dan Jacobson. Matthias Andree. Escalated to "incompatible", 2006-01-13: * Try to obtain FQDN as our own host by default, rather than using "localhost". If hostname cannot be qualified, complain noisily and continue, unless Kerberos, ODMR or ETRN are used (these have always required an FQDN). Partial fix of Debian Bug#150137. Fixes Debian Bug#316454. Matthias Andree # CHANGES RELEVANT TO PACKAGERS AND USERS * fetchmailconf is now a shell wrapper that calls the byte-compiled fetchmailconf.py script, which is now installed in the regular python directory. Matthias Andree. * The --enable-inet6 configure option was removed. The code is mostly protocol agnostic, a fully IPv6 aware OS is expected to provide getaddrinfo(), getnameinfo() and the macro AF_INET6. Matthias Andree. * gettext (intl/) has been removed from the fetchmail package. Install GNU gettext 0.14 separately for NLS (i18n). Matthias Andree * Added Russian translation, courtesy of Pavel Maryanov of the Russian translation team. (MA) * Updated and re-enabled Czech translation, by Miloslav Trmac (MA). * Dropped da=Danish, el=Greek and tr=Turkish translations which have more than 10% (61+) untranslated or fuzzy messages. Matthias Andree. # OTHER USER-VISIBLE CHANGES * Sunil Shetye's fix to force fetchsizelimit to 1 for APOP and RPOP. (ESR) * PopDel.py removed from contrib at author's request. (ESR) * Matthias Andree's fix for Sunil Shetye's fetch-split patch. (ESR) * Include James Stone's moldremover.py script. (ESR) * Enable .fetchmailrc permissions checking under Cygwin. (ESR) * Nalin Dahyabai's fix for POP3 strong authentication. (ESR) * Revised Nalin Dahyabai's fix for POP3 strong authentication (the original version would go into an infinite loop when CAPA failed; found by David Greaves.) (MA) * HOME_ETC patch for PLD Linux. (ESR) * Sunil Shetye's fix for SSL configuration. (ESR) * Simon Josefsson's patch for GSS library support. (ESR) * Added Andrey Lelikov's recipe for Hotmail and Lycos Webmail. (ESR) * Remove blank between MAIL FROM: and <, which causes Cyrus to complain. Patch by Phil Endecott. (RF) * Build fixes for HESIOD and resolv.h trouble on FreeBSD. (MA) * Fabrice Bellet's fix for Red Hat bug #113492, fetchmail hangs in IMAP mode after EXPUNGE when the server (Dovecot 0.99.10) doesn't update RECENT and EXISTS counts. (MA) * Holger Mauermann's bounce patch, to use a NULL envelope from, not write a Return-Path header (both to meet RFC-2821), changed From, added Subject header, rewording the human readable part. Fixes Debian bug #316446. (MA) * Merge Sunil Shetye's time.h handling fix. (MA) * Merge Gerd von Egidy's patch to avoid a segfault in multidrop/received mode when the Received: headers are malformatted. (MA) * MIME-encode bodies and Subject headers of warning messages, limiting the header to 7 bits. (MA) * Normalize most locale codesets to IANA codesets, based on norm_charmap.c by Markus Kuhn. (MA) * Remove sleep(3) after POP3 login, patch by Brian Candler. (MA) * Fix option parsing bug that trashes the showdots setting when more than one server is configured. Patch by Brian Candler. (MA) * Honor sslcertpath setting even if sslcertck is unset. Patch by Brian Candler. (MA) * SSL certificate checking fixes, don't display same error message twice in succession, make sure that Common Name and fingerprint checking are only done once. Print all validation warnings/errors even if not in verbose mode. Patch by Brian Candler. (MA) * Import Bjorn Reese and Daniel Stenberg's MIT-licensed Trio 1.10 from http://daniel.haxx.se/projects/trio/ for systems that do not support snprintf or vsnprintf. (MA) * Clean up the horrible #ifdef HAVE_[V]SNPRINTF that made the code unreadable. Use Trio where [v]snprintf is/are missing. (MA) * Default to Linux 2.2 /proc/net/dev format, and use uname(2) to determine the kernel version instead of calling uname(1). Thanks to Paul Slootman. (MA) * Be more careful when swapping UID lists or writing the .fetchids file, requested by Manfred Weihs. (MA) * Print a warning if multidrop configuration is attempted without envelope option. (MA) * Split information on fetchmail versions before 6.0.0 to a separate OLDNEWS file. (MA) * Merge SuSE patches: (sent by Stanislav Brabec, merged by Matthias Andree) - fetchmail-6.2.5-declaration.patch (double sigint_handler decl/getpass.c) - fetchmail-6.2.5-implicit-declaration.patch (missing #include) - fetchmail-6.2.5-random-result.patch (uninitialized variable/opie.c) * Revised some bogus assertions about POP3 LAST and UIDL use in the manual page. UIDL isn't flaky as the man page suggested, but a reliability feature. In fact, IMAP4 code is flaky in that it relies on the upstream seen flags. (MA) * Miloslav Trmac's patch for fetchmailconf to support string-type values of the "port" variable, avoiding "port None" corruption in .fetchmailrc. To fix Redhat Bug #55623 (MA) * de.po fixes from Nico Golde (MA) * es.po fixes from Jesus Roncero, Debian bug #286044 (MA) * sink.c fix from Cesar Eduardo Barros, to avoid double @ in address when username contains an @ and the envelope sender is null, Debian bug #272289 (MA) * configure.ac cleanups by Miloslav Trmac (MA) * Miloslav Trmac's fix to reply_hack() type, for systems where sizeof(int) != sizeof(size_t). (MA) * Nalin Dahyabhai's fix for driver.c to not call the private Kerberos krb5_init_ets() function. Sent by Miloslav Trmac. (MA) * Nalin Dahyabhai's fix for sink.c/transact.c to reserve sufficient space for \r\n trailers in snprintf calls. Sent by Miloslav Trmac, possibly fixing Red Hat bug #114470. (MA). * Nalin Dahyabhai's patch to use the krb5-config script, if present. Sent by Miloslav Trmac. (MA) * Nalin Dahyabhai's fix to make rpa.c compile. Sent by Miloslav Trmac. (MA) * Trivial fetchmailconf.man to redirect to fetchmail.1. Reported by Miloslav Trmac. (MA) * Internationalization (i18n) updates by Miloslav Trmac. (MA) * Fix "couldn't find canonical DNS name of NN (MM)" for hosts that have only IPv6 addresses. Matthias Andree. * Revised INSTALL after question from Brian Candler, inet6-apps is no longer available: remove inet6-apps hints for IPv6, and add some apologetic message for IPsec. Note the code may be removed in a future version. Matthias Andree. * Brian Candler's FAQ update about SSL certificate verification. (MA) * Nico Golde's patch to support "proto RPOP" in the configuration file, reported by Dr. Andreas Krüger, Debian bug #242384 (MA) * Skip sending POP3 PASS command when USER command failed. Matthias Andree. * Run fetchmail.man through automatic spell checker. Matthias Andree. * Major fetchmail(1) manual page overhaul by R. Hannes Beinert, to clarify singledrop vs. multidrop operation. (MA) * Make tracepolls a server option, as documented. Fixes Debian bug #156094. Matthias Andree. * Fix some minor inaccuracies (RFC-1893 related, grammar/spelling) in the manual page. * Rename ESR's design notes to esrs-design-notes.html and add a new design-notes.html document. The NOTES file will contain both of them. Matthias Andree. * Fix Debian bug #301964, fetchmail leaks sockets when SSL negotiation fails. Fix suggested by Goswin Brederlow. (MA) * Really fix Debian Bug#207919 (garbage in Received: lines when smtphost set), patch by Tobias Diedrich. The 6.2.5 NEWS claimed Gregan's patch had fixed #207919 but it had fixed #212484 instead and #207919 remained unfixed in 6.2.5. The entry below has been corrected to read #212484 now. (MA) * When writing the PID file, write a FHS 2.3 compliant PID file. Fixes Debian bug #230615. Matthias Andree. * Make ODMR really silent, suppress "fetchmail: receiving message data". Fixes Debian Bug#296163. Matthias Andree. * Add From: header to warning emails. Debian Bug#244828. Matthias Andree. * Fix IMAP code to use password of arbitrary length from configuration file (although not when read interactively). Debian Bug#276424. Matthias Andree * Document that fetchmail may automatically enable UIDL option. Debian Bug#304701. Matthias Andree. * Put *BOLD* text into the manual page near --mda to state unmistakably that the --mda %T and %F substitutions add single quotes, hoping to avoid bogus bug reports such as Debian Bug #224564. Matthias Andree * Rename lock_release to fm_lock_release, to avoid namespace collision on Darwin. NetBSD PR#28543 (pkg/28543). Matthias Andree. * The RFC-822 parser no longer strips the last character of bare addresses. Matthias Andree * The IP address matching code was broken and 1. didn't search exhaustively, but matched only the first IP address of the server's queryname against the IP addresses of the server name to match. 2. didn't match IP aliases versus MX hosts. Matthias Andree * The "port" option, while still understood, is being replaced by the "service" option, which is now supported even without --enable-inet6. Matthias Andree. * The default distribution format is now bzip2. Matthias Andree. * fetchmailconf redirects fetchmail's input from /dev/null so it doesn't wait for the user to enter a password when the user doesn't even see the prompt. Reported by Michal Marek. Matthias Andree. * Write RFC-compliant BSMTP envelopes. Reported by Nico Golde. Matthias Andree. * Fix --with-gssapi compilation problem. Simon Josefsson. (MA) * Foster protocol-independence to support IPv6 better, for instance, providing IPv6 addresses in Received: headers. Matthias Andree. * Received: headers now enclose the for <...> destination address in angle brackets for consistency with Postfix. Matthias Andree. * Operating systems that do not support at least one of gethostbyname, gethostbyname_r, getipnodebyname are no longer supported. Matthias Andree. * Fixes to --with-hesiod option. Sunil Shetye. (MA) * Delete oversized messages with the new --limitflush option. Debian Bug#212240. Sunil Shetye. (MA) * Fix MacOS X compilation failures in sink.c (ru_*time has incomplete type). Berlios Bug #4725. Matthias Andree. * Fix "auth ntlm" to send AUTH NTLM (rather than AUTH MSN). Add "auth msn" officially. Reported by Yves Boisjoly. Matthias Andree * Expunge between IMAP folders when polling multiple folders. Sunil Shetye. (MA) * Fix IMAP expunged message counting. Sunil Shetye. (MA) * Add full support for --service option. Matthias Andree * When getaddrinfo() fails resolving a service, log getaddrinfo() error. (MA) * Fix bogus "cannot resolve service * to port number" error. Simon Barner. (MA) * Failure to set up SSL connections now results in PS_SOCKET. Suggested by Thomas Wolff. Matthias Andree. * Kerberos IV detection fix for FreeBSD 4. Simon Barner. (MA) * Fix display and documentation of --envelope option. Matthias Andree * Make "envelope 'Delivered-To'" work with dropdelivered. Timothy Lee. (MA) * Add -DBIND_8_COMPAT to Darwin (MacOS X) compiles, to fix build problems on newer Darwin versions. Matthias Andree. * fetchmail should now automatically detect if OpenSSL requires -ldl. Matthias Andree. * Fix Solaris build with --disable-nls (blastwave.org). Matthias Andree. * Missed --port/--service/--ssl cleanups in the manual. Reminder from Thomas Wolff. (MA) * Complain in POP3 if NTLM/MSN auth is requested but had not been enabled at compile time. This configuration mismatch now causes an error message and authentication failure. Found by Yves Boisjoly. Matthias Andree * fetchmailconf now allows expert users to choose the authorization type and also offers MSN and NTLM, suggested by Yves Boisjoly. Matthias Andree * fetchmailconf now (as of 1.49) writes its version to the comment of the saved run control file. Matthias Andree * Properly shut down SSL connections. Berlios Patch #647 by Arkadiusz Miśkiewicz. (MA) * Global variable cleanup, to fix daemon mode reinitialization problems. Patch by Sunil Shetye. (MA) * fetchmailconf -h documents the fetchmailconf -h option. Matthias Andree * fetchmailconf -V now prints the fetchmailconf version. Matthias Andree * Add support for SubjectAltName (RFC-2595 or 2818), to avoid bogus certificate mismatch errors. Patch by Roland Stigge, Debian Bug#201113. (MA) * make fetchmail --silent --quit really silent, Debian Bug #229014 by Dr. Andreas Krüger. Matthias Andree * cleanup --quit handling again (so that --silent --quit just kills the existing daemon, rather than continue running), and document it more clearly. Matthias Andree * Print an error message if multiple "defaults" records are found in the configuration file. Matthias Andree * Bury on_exit officially - the necessary code had been missing from 6.0.0, 6.2.0, 6.2.5. Matthias Andree * Exit with error if the lock file cannot be read. Matthias Andree * Exit with error if the lock file cannot be created exclusively, this got broken in a 6.2.6-pre, 6.2.5.2 and older were fine. Matthias Andree * Do not break some other process's lockfile in "-q" mode, but wait for the other process's exit. Matthias Andree * Man page: --sslfingerprint points user to x509(1ssl) and gives an example how to use it. Debian Bug#213484, Eduard Bloch. (MA) * fetchmailconf now sets the service properly after autoprobe. Fixes Debian Bug#320645. Matthias Andree * Man page: Fix Debian Bug#241883, making global options more clear. Matt Swift, Matthias Andree. * When eating IMAP message trailer, don't see any line containing "OK" as the end of the trailer, but wait for the proper tagged OK line. To work around the qmail + Courier-IMAP problem in Debian Bug#338007. Matthias Andree * Fix Debian Bug#317761: when trying to send a bounce message, don't bail out if we cannot qualify our own hostname, so we aren't losing the bounce. Instead, pass the buck on to the SMTP server and use our own unqualified hostname. Matthias Andree * Revise some error messages so they are less confusing. Sunil Shetye. * Man page: update --smtphost documentation. Sunil Shetye, Matthias Andree. * Man page: clarify --loghost works only while detached. Matthias Andree * Man page: update --smtpaddress documentation. Sunil Shetye. * Fix several memory leaks and bugs in the SMTP/LMTP retry logic where fetchmail confused UNIX and Internet domain sockets. Sunil Shetye. * Man page (BUGS): document that passwords are length limited. Matthias Andree * Man page: Document that quoted strings that run across line boundaries contain the control characters (CR or LF). Document explicitly the backslash escape sequences and their differences from the escape sequences used in the C programming language.
