Name : dovecot
Product : Fedora 20
Version : 2.2.16
Release : 2.fc20
URL : http://www.dovecot.org/
Summary : Secure imap and pop3 server
Description :
Dovecot is an IMAP server for Linux/UNIX-like systems, written with security

Update Information:

fixes CVE-2015-3420: SSL/TLS handshake failures leading to a crash of the login process
– dovecot updated to 2.2.16
– auth: Don’t crash if master user login is attempted without
any configured master=yes passdbs
– Parsing UTF-8 text for mails could have caused broken results
sometimes if buffering was split in the middle of a UTF-8 character.
This affected at least searching messages.
– String sanitization for some logged output wasn’t done properly:
UTF-8 text could have been truncated wrongly or the truncation may
not have happened at all.
– fts-lucene: Lookups from virtual mailbox consisting of over 32
physical mailboxes could have caused crashes.
– dovecot updated to 2.2.16
– auth: Don’t crash if master user login is attempted without
any configured master=yes passdbs
– Parsing UTF-8 text for mails could have caused broken results
sometimes if buffering was split in the middle of a UTF-8 character.
This affected at least searching messages.
– String sanitization for some logged output wasn’t done properly:
UTF-8 text could have been truncated wrongly or the truncation may
not have happened at all.
– fts-lucene: Lookups from virtual mailbox consisting of over 32

– Fixed infinite loop in message parsing if message ends with
“–boundary” and CR (without LF). Messages saved via SMTP/LMTP can’t
trigger this, because messages must end with an “LF.”. A user could
trigger this for him/herself though.
– lmtp: Client was sometimes disconnected before all the output was
sent to it.
– replicator: Database wasn’t being exported to disk every 15 minutes
as it should have. Instead it was being imported, causing “doveadm
replicator remove” commands to not work very well.
