Category:Red Hat Local Security Checks
Title:RedHat Update for libXfont RHSA-2014:0018-01
Summary:The remote host is missing an update for the 'libXfont'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'libXfont'
package(s) announced via the referenced advisory.

Vulnerability Insight:
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.

Affected Software/OS:
libXfont on Red Hat Enterprise Linux (v. 5 server),
Red Hat Enterprise Linux Desktop (v. 6),
Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)

Solution:
Please Install the Updated Packages.
