* Clear SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS without SSL_CTX_clear_options()Earl Chew2012-09-031-3/+4
| | | | | | | | | | | | A patch to clear SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS was added recently: http://gitorious.org/fetchmail/fetchmail/commit/48809c5b9f6c9081f4031fa938dd63b060c18a4b?format=patch Older implementations of OpenSSL do not support SSL_CTX_clear_options(). This patch reworks the previous change to avoid the use of SL_CTX_clear_options() and instead clears the corresponding bit in SSL_OP_ALL before calling SSL_CTX_set_options().
* Fix CVE-2011-3389 by clearing SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS...Matthias Andree2012-05-031-0/+6
| | | | | | | ...from SSL options, unless FETCHMAIL_DISABLE_CBC_IV_COUNTERMEASURE is a non-empty environment variable. Suggested by Apple.
* Fix build on SSLv2-disabled OpenSSL setupsMatthias Andree2011-10-261-0/+5
| | | | | | | | 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 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.

* Revert SO_???TIMEO-based STARTTLS timeout handling.Matthias Andree2011-05-261-28/+1
| | | | | | | | | This reverts commits 47c05b10018f5ec7493e4bd9f521aaa18d96f1e2 and 72ce8bce8dd655b6aefa33d0a74e883dad5202b5, the code isn't portable, for instance, Solaris does not support SO_RCVTIMEO/SO_SNDTIMEO. These socket-level options are known, but Solaris returns EAFNOSUPPORT. Reported by Jonathan Buschmann.

* Remove support for SSLv2 (fixes Debian Bug #622054).Matthias Andree2011-04-111-5/+3
| | | | | | | | | | | | | SSLv2 has been deprecated since 1996, and is insecure. Remove --sslproto SSL2 support. Set SSL_OP_NO_SSLvSSL_CTX 2 option so that the SSLv23 multi-version client no longer negotiates SSLv2. Note that some distributions (such as Debian) build OpenSSL 1.0.0 without SSLv2 support, so on those, the build would fail.

* --sslcert{file|path} overrides default store, add environment var...Matthias Andree2010-04-231-9/+18
| | | | | | | | | | If at least one of --sslcertfile and --sslcertpath is given, fetchmail skips loading the default OpenSSL X.509 trusted CA cert locations. If the environment variable FETCHMAIL_INCLUDE_DEFAULT_X509_CA_CERTS is set to a non-empty value, fetchmail will additionally load the default locations. The old FETCHMAIL_NO_DEFAULT_X509_PATHS variable was dropped.
* Add --sslcertfile option and FETCHMAIL_NO_DEFAULT_X509_PATHS env var,Matthias Andree2010-04-181-5/+12

* case-insensitive check of SSL fingerprints (Daniel Richard G.)Matthias Andree2009-01-221-1/+1
| | | | | | | | | | | | | | | | | | | | Daniel Richard G. writes: | I was clearing out an old Fetchmail SVN checkout I had lying around | here, and came across one small change that I forgot to send in. | | In socket.c, there's a bit of code that compares SSL certificate | fingerprints: [...] | | That strcmp() call should be an strcasecmp(). At one point, I | encountered a certificate where the fingerprint's hex digits were in a | different case than what was expected, and the connection attempt failed | because of that. Not exactly what you'd call a potential MitM attack | :-) He's right, we can compare case-insensitively without sacrificing fetchmail's security, so let's just do that for the sake of ease of use. svn path=/branches/BRANCH_6-3/; revision=5262
