CentOS 5 / 6 : libXfont (CESA-2014:0018)

high Nessus Plugin ID 71901

Synopsis

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

Description

Updated libXfont packages that fix one security issue are now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having important 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.

The libXfont packages provide the X.Org libXfont runtime library.
X.Org is an open source implementation of the X Window System.

A stack-based buffer overflow flaw was found in the way the libXfont library parsed Glyph Bitmap Distribution Format (BDF) fonts. A malicious, local user could exploit this issue to potentially execute arbitrary code with the privileges of the X.Org server.
(CVE-2013-6462)

Users of libXfont should upgrade to these updated packages, which contain a backported patch to resolve this issue. All running X.Org server instances must be restarted for the update to take effect.

Solution

Update the affected libxfont packages.
