   mail/dovecot2: update to 2.3.13

   Update mail/dovecot2 pacakge to 2.3.13, including security fixes.

   v2.3.13 2021-01-04	Aki Tuomi <aki.tuomi@open-xchange.com>

   	* CVE-2020-24386: Specially crafted command can cause IMAP hibernate to
   	  allow logged in user to access other people's emails and filesystem
   	  information.
   	* Metric filter and global event filter variable syntax changed to a
   	  SQL-like format. See https://doc.dovecot.org/configuration_manual/event_filter/
   	* auth: Added new aliases for %{variables}. Usage of the old ones is
   	  possible, but discouraged.
   	* auth: Removed RPA auth mechanism, SKEY auth mechanism, NTLM auth
   	  mechanism and related password schemes.
   	* auth: Removed passdb-sia, passdb-vpopmail and userdb-vpopmail.
   	* auth: Removed postfix postmap socket
   	+ auth: Added new fields for auth server events. These fields are now
   	  also available for all auth events. See
   	  https://doc.dovecot.org/admin_manual/list_of_events/#authentication-server
   	  for details.
   	+ imap-hibernate: Added imap_client_hibernated, imap_client_unhibernated
   	  and imap_client_unhibernate_retried events. See
   	  https://doc.dovecot.org/admin_manual/list_of_events/ for details.
   	+ lib-index: Added new mail_index_recreated event. See
   	  https://doc.dovecot.org/admin_manual/list_of_events/#mail-index-recreated
   	+ lib-sql: Support TLS options for cassandra driver. This requires
   	  cpp-driver v2.15 (or later) to work reliably.
   	+ lib-storage: Missing $HasAttachment / $HasNoAttachment flags are now
   	  added to existing mails if mail_attachment_detection_option=add-flags
   	  and it can be done inexpensively.
   	+ login proxy: Added login_proxy_max_reconnects setting (default 3) to
   	  control how many reconnections are attempted.
   	+ login proxy: imap/pop3/submission/managesieve proxying now supports
   	  reconnection retrying on more than just connect() failure. Any error
   	  except a non-temporary authentication failure will result in reconnect
   	  attempts.
   	- auth: Lua passdb/userdb leaks stack elements per call, eventually
   	  causing the stack to become too deep and crashing the auth or
   	  auth-worker process.
   	- auth: SASL authentication PLAIN mechanism could be used to trigger
   	  read buffer overflow. However, this doesn't seem to be exploitable in
   	  any way.
   	- auth: v2.3.11 regression: GSSAPI authentication fails because dovecot
   	  disallows NUL bytes for it.
   	- dict: Process used too much CPU when iterating keys, because each key
   	  used a separate write() syscall.
   	- doveadm-server: Crash could occur if logging was done outside command
   	  handling. For example http-client could have done debug logging
   	  afterwards, resulting in either segfault or
   	  Panic: file http-client.c: line 642 (http_client_context_close):
   	  assertion failed: (cctx->clients_list == NULL).
   	- doveadm-server: v2.3.11 regression: Trying to connect to doveadm server
   	  process via starttls assert-crashed if there were no ssl=yes listeners:
   	  Panic: file master-service-ssl.c: line 22 (master_service_ssl_init):
   	  assertion failed: (service->ssl_ctx_initialized).
   	- fts-solr: HTTP requests may have assert-crashed:
   	  Panic: file http-client-request.c: line 1232 (http_client_request_send_more):
   	  assertion failed: (req->payload_input != NULL)
   	- imap: IMAP NOTIFY could crash with a segmentation fault due to a bad
   	  configuration that causes errors. Sending the error responses to the
   	  client can cause the segmentation fault. This can for example happen
   	  when several namespaces use the same mail storage location.
   	- imap: IMAP NOTIFY used on a shared namespace that doesn't actually
   	  exist (e.g. public namespace for a nonexistent user) can crash with a panic:
   	  Panic: Leaked view for index /tmp/home/asdf/mdbox/dovecot.list.index: \ 
Opened in (null):0
   	- imap: IMAP session can crash with QRESYNC extension if many changes
   	  are done before asking for expunged mails since last sync.
   	- imap: Process might hang indefinitely if client disconnects after
   	  sending some long-running commands pipelined, for example FETCH+LOGOUT.
   	- lib-compress: Mitigate crashes when configuring a not compiled in
   	  compression. Errors with compression configuration now distinguish
   	  between not supported and unknown.
   	- lib-compression: Using xz/lzma compression in v2.3.11 could have
   	  written truncated output in some situations. This would result in
   	  "Broken pipe" read errors when trying to read it back.
   	- lib-compression: zstd compression could have crashed in some situations:
   	  Panic: file ostream.c: line 287 (o_stream_sendv_int): assertion failed: \ 
(!stream->blocking)
   	- lib-dict: dict client could have crashed in some rare situations when
   	  iterating keys.
   	- lib-http: Fix several assert-crashes in HTTP client.
   	- lib-index: v2.3.11 regression: When mails were expunged at the same
   	  time as lots of new content was being saved to the cache (e.g. cache
   	  file was lost and is being re-filled) a deadlock could occur with
   	  dovecot.index.cache / dovecot.index.log.
   	- lib-index: v2.3.11 regression: dovecot.index.cache file was being
   	  purged (rewritten) too often when it had a field that hadn't been
   	  accessed for over 1 month, but less than 2 months. Every cache file
   	  change caused a purging in this situation.
   	- lib-mail: MIME parts were not returned correctly by Dovecot MIME parser.
   	  Regression caused by fixing CVE-2020-12100.
   	- lib-mail: When max nested MIME parts were reached, IMAP BODYSTRUCTURE
   	  was written in a way that may have caused confusion for both IMAP
   	  clients and Dovecot itself when parsing it. The truncated part is now
   	  written out using application/octet-stream MIME type.
   	- lib-mail: v2.3.11 regression: Mail delivery / parsing crashed when the
   	  10000th MIME part was message/rfc822 (or if parent was multipart/digest):
   	  Panic: file message-parser.c: line 167 (message_part_append):
   	  assertion failed: (ctx->total_parts_count <= \ 
ctx->max_total_mime_parts).
   	- lib-oauth2: Dovecot incorrectly required oauth2 server introspection
   	  reply to contain username with invalid token.
   	- lib-ssl-iostream, lib-dcrypt: Fix building with OpenSSL that has
   	  deprecated APIs disabled.
   	- lib-storage: When mail's size is different from the cached one (in
   	  dovecot.index.cache or Maildir S=size in the filename), this is
   	  handled by logging "Cached message size smaller/larger than expected"
   	  error. However, in some situations this also ended up crashing with:
   	  Panic: file istream.c: line 315 (i_stream_read_memarea):
   	  assertion failed: (old_size <= _stream->pos - _stream->skip).
   	- lib-storage: v2.3 regression: Copying/moving mails was taking much more
   	  memory than before. This was mainly visible when copying/moving
   	  thousands of mails in a single transaction.
   	- lib-storage: v2.3.11 regression: Searching messages assert-crashed
   	  (without FTS): Panic: file message-parser.c: line 174 (message_part_finish):
   	  assertion failed: (ctx->nested_parts_count > 0).
   	- lib: Dovecot v2.3 moved signal handlers around in ioloops,
   	  causing more CPU usage than in v2.2.
   	- lib: Fixed JSON parsing: '\' escape sequence may have wrongly resulted
   	  in error if it happened to be at read boundary. Any NUL characters and
   	  '\u0000' will now result in parsing error instead of silently
   	  truncating the data.
   	- lmtp, submission: Server may hang if SSL client connection disconnects
   	  during the delivery. If this happened repeated, it could have ended
   	  up reaching process_limit and preventing any further lmtp/submission
   	  deliveries.
   	- lmtp: Proxy does not always properly log TLS connection problems as
   	  errors; in some cases, only a debug message is logged if enabled.
   	- lmtp: The LMTP service can hang when commands are pipelined. This can
   	  particularly occur when one command in the middle of the pipeline fails.
   	  One example of this occurs for proxied LMTP transactions in which the
   	  final DATA or BDAT command is pipelined after a failing RCPT command.
   	- login-proxy: The login_source_ips setting has no effect, and therefore
   	  the proxy source IPs are not cycled through as they should be.
   	- master: Process was using 100% CPU in some situations when a broken
   	  service was being throttled.
   	- pop3-login: POP3 login would fail with "Input buffer full" if the
   	  initial response for SASL was too long.
   	- stats: Crash would occur when generating openmetrics data for metrics
   	  using aggregating functions.
