Test ID:1.3.6.1.4.1.25623.1.0.871195
Category:Red Hat Local Security Checks
Title:RedHat Update for dovecot RHSA-2014:0790-01
Summary:The remote host is missing an update for the 'dovecot'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'dovecot'
package(s) announced via the referenced advisory.

Vulnerability Insight:
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.

Affected Software/OS:
dovecot on Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Server (v. 7),
Red Hat Enterprise Linux Workstation (v. 6)

Solution:
Please Install the Updated Packages.
