high Nessus Plugin ID 71909

Language:

Synopsis

The remote Red Hat 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, libXfont-debuginfo and / or libXfont-devel packages.
