CentOS 6 : dovecot (CESA-2014:0790)

medium Nessus Plugin ID 76218

Synopsis

The remote CentOS host is missing one or more security updates.

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.

Solution

Update the affected dovecot packages.
