- bsc#1119850
  dsync crashes if ACL user identifier is matched and then not matched
  Was fixed by update to 2.3.3

Mon Oct  1 22:55:38 UTC 2018 - Marcus Rueckert <>

- update pigeonhole to 0.5.3
  - Fix assertion panic occurring when managesieve service fails to
    open INBOX while saving a Sieve script. This was caused by a
    lack of cleanup after failure.
  - Fix specific messages causing an assert panic with actions that
    compose a reply (e.g. vacation). With some rather weird input
    from the original message, the header folding algorithm (as
    used for composing the References header for the reply) got
    confused, causing the panic.
    parsing.  After finishing reading the Sieve script, the command
    parsing sometimes didn't continue with the search arguments.
    This is a time- critical bug that likely only occurs when the
    Sieve script is sent in the next TCP frame.

- update to 2.3.2
  * old-stats plugin: Don't temporarily enable PR_SET_DUMPABLE
    while opening /proc/self/io. This may still cause security
    problems if the process is ptrace()d at the same time.
    Instead, open it while still running as root.
  + doveadm: Added mailbox cache decision&remove commands. See
    doveadm-mailbox(1) man page for details.

  - doveadm-server: TCP connections are hanging when there is a lot
    of network output. This especially caused hangs in
  - Using multiple type=shared mdbox namespaces crashed
  - mail_fsync setting was ignored. It was always set to
  - lua auth: Fix potential crash at deinit
  - SSL/TLS servers may have crashed if client disconnected during
  - SSL/TLS servers: Don't send extraneous certificates to client
    when alt certs are used.
  - lda, lmtp: Return-Path header without '<' may have
  - lda, lmtp: Unencoded UTF-8 in email address headers may
  - lda: -f parameter didn't allow empty/null/domainless address
  - lmtp, submission: Message size limit was hardcoded to 40 MB.
    Exceeding it caused the connection to get dropped during
  - lmtp: Fix potential crash when delivery fails at DATA stage
  - lmtp: login_greeting setting was ignored
  - Fix to work with OpenSSL v1.0.2f

  - cassandra: Fix consistency=quorum to work
  - dsync: Lock file generation failed if home directory didn't
  - Snippet generation for HTML mails didn't ignore &entities
    inside blockquotes, producing strange looking snippets.
  - imapc: Fix assert-crash if getting disconnected and after
    reconnection all mails in the selected mailbox are gone.
  - pop3c: Handle unexpected server disconnections without
  - fts: Fixes to indexing mails via virtual mailboxes.

    wasn't indexed.
  - Obsolete dovecot.index.cache offsets were sometimes used.
    Trying to fetch a field that was just added to cache file may
    not have always found it.
- update pigeonhole to 0.5.2
  + Implement plugin for the a vendor-defined IMAP capability
    called "FILTER=SIEVE". It adds the ability to manually invoke
    Sieve filtering in IMAP. More information can be found in
  - The Sieve addess test caused an assertion panic for invalid
    addresses with UTF-8 codepoints in the localpart. Fixed by
    properly detecting invalid addresses with UTF-8 codepoints in
    the localpart and skipping these like other invalid addresses
    while iterating addresses for the address test.
  - Make the length of the subject header for the vacation response
    configurable and enforce the limit in UTF-8 codepoints rather
    than bytes. The subject header for a vacation response was
    statically truncated to 256 bytes, which is too limited for
    multi-byte UTF-8 characters.
  - Sieve editheader extension: Fix assertion panic occurring when
    it is used to manipulate a message header with a very large
    header field.
  - Properly abort execution of the sieve_discard script upon
    error.  Before, the LDA Sieve plugin attempted to execute the
    sieve_discard script when an error occurs. This can lead to the
    message being lost.
  - Fix the interaction between quota and the sieve_discard script.
    When quota was used together with a sieve_discard script, the
    message delivery did not bounce when the quota was exceeded.
- refreshed to apply cleanly again dovecot-2.3.0-better_ssl_defaults.patch

  - Explicitly disallow UTF-8 in localpart in addresses parsed from
    Sieve script.
  - editheader extension: Corrected the stream position
    calculations performed while making the modified message
    available as a stream.  Pigeonhole Sieve crashed in LMTP with
    an assertion panic when the Sieve editheader extension was used
    before the message was redirected.  Experiments indicate that
    the problem occurred only with LMTP and that LDA is not
  - fileinto extension: Fix assert panic occurring when fileinto is
    used without being listed in the require line, while the copy
    extension is listed there. This is a very old bug.
  - imapsieve plugin: Do not assert crash or log an error for
    messages that disappear concurrently while applying Sieve
    scripts. This event is now logged as a debug message.
  - Sieve extprograms plugin: Large output from "execute" command
    crashed delivery. Fixed buffering issue in code that handles
    output from the external program.

- update to
  * CVE-2017-15130: TLS SNI config lookups may lead to excessive
    memory usage, causing imap-login/pop3-login VSZ limit to be
    reached and the process restarted. This happens only if Dovecot
    config has local_name { } or local { } configuration blocks and
    attacker uses randomly generated SNI servernames. (boo#1082828)
  * 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. (boo#1075608)
  * 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

- 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

     If you upgrade from 2.2: Config file changes:
     - Removed:
     - Added:

   * 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 for
   * 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.
   - 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
   - Many other smaller fixes
- patches:
  - dovecot-2.3.0-better_ssl_defaults.patch
  - dovecot-2.3.0-dont_use_etc_ssl_certs.patch
