Aki Tuomi reports:

+
Vulnerability Details: +When reading FTS or POP3-UIDL header from dovecot index, the input +buffer size is not bound, and data is copied to target structure causing +stack overflow. + +Risk: +This can be used for local root privilege escalation or executing +arbitrary code in dovecot process context. This requires ability to +directly modify dovecot indexes. +Steps to reproduce: +Produce dovecot.index.log entry that creates an FTS header which has +more than 12 bytes of data. +Trigger dovecot indexer-worker or run doveadm index. +Dovecot will crash. + +Mitigations: +Since 2.3.0 dovecot has been compiled with stack smash protection, ASLR, +read-only GOT tables and other techniques that make exploiting this bug +much harder.
