Description


Updated dovecot packages that fix one security issue are now available for
Red Hat Enterprise Linux 6 and 7.

The Red Hat Security Response Team has rated this update as having Moderate
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.

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.
