Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated pixman 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.

Pixman is a pixel manipulation library for the X Window System and
Cairo.

An integer overflow, which led to a heap-based buffer overflow, was
found in the way pixman handled trapezoids. If a remote attacker could
trick an application using pixman into rendering a trapezoid shape
with specially crafted coordinates, it could cause the application to
crash or, possibly, execute arbitrary code with the privileges of the
user running the application. (CVE-2013-6425)

Users are advised to upgrade to these updated packages, which contain
a backported patch to correct this issue. All applications using
pixman must be restarted for this update to take effect.
