* imap.c, pop3.c: fix protocol regression of 6.4.22.rc1Matthias Andree2021-08-273-68/+82
| | | | | | | | | | | | | | | fetchmail 6.4.22.rc1 clobbered its IMAP state too late, and lost information on the protocol version in many circumstances. Consequently, it tried to talk IMAP4 to IMAP4rev1 servers, which failed. This fix the clear_sessiondata() out to the new constructor and destructor, such that imap_getauth() only needs to call it after STARTTLS, when it must re-probe CAPABILITY anyways. This was the same bug for POP3, which however does not collect state from the greeting, so that the bug was without effect for POP3. Reported by: Corey Halpin, FreeBSD port maintainer.

* struct method: introduce con-/destructorsMatthias Andree2021-08-272-0/+13
| | | | | | | These can be used before setting up or after closing down a socket for protocol-specific initialisiation or cleanup, and are required to cleanly fix up the IMAP-loses-protocol-version regression without too many temporary hacks in the code.

| | | | | | | | Reported by Bjørn Mork, fixes Debian Bug#992400. Crash happens inside xstrdup() on a strlen((char *)-1) where the argument is constant and the trigger is a local trusted configuration file, so not deemed a vulnerability.

| | | | | | | | | | On --sslproto auto (or other nonempty values), when receiving IMAP PREAUTH state, abort the connection, rather than continuing with cleartext. --ssl is unaffected because it always negotiates TLS. See fetchmail-SA-2021-02.txt for details.

* Fix --logfile and message truncation issue.Matthias Andree2021-08-092-1/+20
| | | | | | | | | | | | | | | | | Regression in 6.4.20's security fix (Git commit c546c829). We doubly incremented partial_message_size_used on modern systems (stdard.h/vsnprintf), once in report_vbuild() and then again in report_build(), so the 2nd and subsequent report_build() fragments landed too late in the buffer. This will not cause overruns due to the reallocation prior to the vsnprintf/sprintf, but it write starts behind the '\0' byte, instead of right over it, so the string also gets truncated to the first fragment written with report_vbuild(). Fix by moving the increment back into the #else...#endif part that does not use report_vbuild(). Reported by: Jürgen Edner, Erik Christiansen
