3. Description:
Dovecot is an IMAP server, written with security primarily in mind, for
Linux and other UNIX-like systems. It also contains a small POP3 server.
It supports mail in both the maildir or mbox format. The SQL drivers and
authentication plug-ins are provided as subpackages.
It was discovered that Dovecot did not properly discard connections trapped
in the SSL/TLS handshake phase. A remote attacker could use this flaw to
cause a denial of service on an IMAP/POP3 server by exhausting the pool of
available connections and preventing further, legitimate connections to the
IMAP/POP3 server to be made. (CVE-2014-3430)
All dovecot users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. After installing the
updated packages, the dovecot service will be restarted automatically.
4. Solution:
