The remote Red Hat host is missing a security update for xorg-x11-server.

Description

The remote Redhat Enterprise Linux 5 / 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2013:1868 advisory.

X.Org is an open source implementation of the X Window System. It provides the basic low-level functionality that full-fledged graphical user interfaces are designed upon.

An integer overflow, which led to a heap-based buffer overflow, was found in the way X.Org server handled trapezoids. A malicious, authorized client could use this flaw to crash the X.Org server or, potentially, execute arbitrary code with root privileges. (CVE-2013-6424)

All xorg-x11-server users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
