This happens only if Dovecot config has local_name { } or local { } configuration blocks and attacker uses randomly generated SNI servernames. * CVE-2017-14461: Parsing invalid email addresses may cause a crash or leak memory contents to attacker. For example, these memory contents might contain parts of an email from another user if the same imap process is reused for multiple users. First discovered by Aleksandar Nikolic of Cisco Talos. Independently also discovered by "flxflndy" via HackerOne. * CVE-2017-15132: Aborted SASL authentication leaks memory in login process. * Linux: Core dumping is no longer enabled by default via PR_SET_DUMPABLE, because this may allow attackers to bypass chroot/group restrictions. Found by cPanel Security Team. Nowadays core dumps can be safely enabled by using "sysctl -w fs.suid_dumpable=2". If the old behaviour is wanted, it can still be enabled by setting: import_environment=$import_environment PR_SET_DUMPABLE=1 - imap-login with SSL/TLS connections may end up in infinite loop ------------------------------------------------------------------- Mon Dec 25 22:39:53 UTC 2017 - jengelh@inai.de - Replace %__-type macro indirections. Replace xargs rm by built in -delete of find(1). - Run ldconfig directly via %post -p. - Check for users in %pre before creating them, and do not suppress errors about it. ------------------------------------------------------------------- Mon Dec 25 18:47:35 UTC 2017 - mrueckert@suse.de - backport 321a39be974deb2e7eff7b2a509a3ee6ff2e5ae1.patch fixes crash with imap sieve ------------------------------------------------------------------- Sun Dec 24 02:04:25 UTC 2017 - mrueckert@suse.de - Move the example-config + mkcert.sh to /usr/share/dovecot This makes the files no longer documentation and they actually exist on e.g. our docker image, where rpms are installed without documentation. (boo#1070871) ------------------------------------------------------------------- Wed Dec 20 10:32:23 UTC 2017 - mrueckert@suse.de - starting 2.3 package based on the latest 2.2 branch There are several new and exciting features in v2.3.0. I'm especially happy about the new logging and statistics code, which will allow us to generate statistics for just about everything. We didn't have time to implement everything we wanted for them yet, and there especially aren't all that many logging events yet that can be used for statistics. We'll implement those to v2.3.1, which might also mean that some of the APIs might still change in v2.3.1 if that's required. We also have new lib-smtp server code, which was used to implement SMTP submission server and do a partial rewrite for LMTP server. Some of the larger changes: * Various setting changes, see https://wiki2.dovecot.org/Upgrading/2.3 If you upgrade from 2.2: Config file changes: - Removed: /etc/dovecot/conf.d/11-object-storage.conf - Added: /etc/dovecot/conf.d/20-submission.conf * Logging rewrite started: Logging is now based on hierarchical events. This makes it possible to do various things, like: 1) giving consistent log prefixes, 2) enabling debug logging with finer granularity, 3) provide logs in more machine readable formats (e.g. json). Everything isn't finished yet, especially a lot of the old logging code still needs to be translated to the new way. * Statistics rewrite started: Stats are now based on (log) events. It's possible to gather statistics about any event that is logged. See http://wiki2.dovecot.org/Statistics for details * ssl_dh setting replaces the old generated ssl-parameters.dat * IMAP: When BINARY FETCH finds a broken mails, send [PARSE] error instead of [UNKNOWNCTE] * Linux: core dumping via PR_SET_DUMPABLE is no longer enabled by default due to potential security reasons (found by cPanel Security Team). + Added support for SMTP submission proxy server, which includes support for BURL and CHUNKING extension. + LMTP rewrite. Supports now CHUNKING extension and mixing of local/proxy recipients. + auth: Support libsodium to add support for ARGON2I and ARGON2ID password schemes. + auth: Support BLF-CRYPT password scheme in all platforms + auth: Added LUA scripting support for passdb/userdb. See https://wiki2.dovecot.org/AuthDatabase/Lua - Input streams are more reliable now when there are errors or when the maximum buffer size is reached. Previously in some situations this could have caused Dovecot to try to read already freed memory. - Output streams weren't previously handling failures when writing a trailer at the end of the stream. This mainly affected encrypt and zlib compress ostreams, which could have silently written truncated files if the last write happened to fail (which shouldn't normally have ever happened). - virtual plugin: Fixed panic when fetching mails from virtual mailboxes with IMAP BINARY extension. - doveadm-server: Fix potential hangs with SSL connections - doveadm proxy: Reading commands' output from v2.2.33+ servers could have caused the output to be corrupted or caused a crash. - Many other smaller fixes - patches: - dovecot-2.3.0-better_ssl_defaults.patch - dovecot-2.3.0-dont_use_etc_ssl_certs.patch
