Branch: CURRENT, Version: 2.3.0.1nb1, Package name: dovecot-2.3.0.1nb1, Maintainer: adam

Dovecot is an open source IMAP and POP3 server for Linux/UNIX-like systems,
written with security primarily in mind. Dovecot is an excellent choice for both
small and large installations. It's fast, simple to set up, requires no special
administration and it uses very little memory.


Required to run:
[archivers/lz4]

Required to build:

Log message:
mail/dovecot2: update to 2.3.0.1

Small patch release to fix the worst bugs in v2.3.0. v2.3.1 is coming in about a \ 
month with a lot more changes.

 * 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.
 * 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

Log message:
Update mail/dovecot2* to 2.3.0.

Some of the larger changes:

* Various setting changes, see https://wiki2.dovecot.org/Upgrading/2.3
* 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

dovecot2: update to 2.2.33.2

2.2.33.2:
- doveadm: Fix crash in proxying (or dsync replication) if remote is
  running older than v2.2.33
- auth: Fix memory leak in %{ldap_dn}
- dict-sql: Fix data types to work correctly with Cassandra

Log message:
dovecot2: update to 2.2.33.1

v2.2.33.1:
- dovecot-lda was logging to stderr instead of to the log file.

v2.2.33:
* doveadm director commands wait for the changes to be visible in the
  whole ring before they return. This is especially useful in testing.
* Environments listed in import_environment setting are now set or
  preserved when executing standalone commands (e.g. doveadm)

+ doveadm proxy: Support proxying logs. Previously the logs were
  visible only in the backend's logs.
+ Added %{if}, see https://wiki2.dovecot.org/Variables#Conditionals
+ Added a new notify_status plugin, which can be used to update dict
  with current status of a mailbox when it changes. See
  https://wiki2.dovecot.org/Plugins/NotifyStatus
+ Mailbox list index can be disabled for a namespace by appending
  ":LISTINDEX=" to location setting.
+ dsync/imapc: Added dsync_hashed_headers setting to specify which
  headers are used to match emails.
+ pop3-migration: Add pop3_migration_ignore_extra_uidls=yes to ignore
  mails that are visible in POP3 but not IMAP. This could happen if
  new mails were delivered during the migration run.
+ pop3-migration: Further improvements to help with Zimbra
+ pop3-migration: Cache POP3 UIDLs in imapc's dovecot.index.cache
  if indexes are enabled. These are used to optimize incremental syncs.
+ cassandra, dict-sql: Use prepared statements if protocol version>3.
+ auth: Added %{ldap_dn} variable for passdb/userdb ldap
- acl: The "create" (k) permission in global acl-file was sometimes
  ignored, allowing users to create mailboxes when they shouldn't have.
- sdbox: Mails were always opened when expunging, unless
  mail_attachment_fs was explicitly set to empty.
- lmtp/doveadm proxy: hostip passdb field was ignored, which caused
  unnecessary DNS lookups if host field wasn't an IP
- lmtp proxy: Fix crash when receiving unexpected reply in RCPT TO
- quota_clone: Update also when quota is unlimited (broken in v2.2.31)
- mbox, zlib: Fix assert-crash when accessing compressed mbox
- doveadm director kick -f parameter didn't work
- doveadm director flush <host> resulted flushing all hosts, if <host>
  wasn't an IP address.
- director: Various fixes to handling backend/director changes at
  abnormal times, especially while ring was unsynced. These could have
  resulted in crashes, non-optimal behavior or ignoring some of the
  changes.
- director: Use less CPU in imap-login processes when moving/kicking
  many users.
- lmtp: Session IDs were duplicated/confusing with multiple RCPT TOs
  when lmtp_rcpt_check_quota=yes
- doveadm sync -1 fails when local mailboxes exist that do not exist
  remotely. This commonly happened when lazy_expunge mailbox was
  autocreated when incremental sync expunged mails.
- pop3: rawlog_dir setting didn't work
