Synopsis :

The remote Oracle Linux host is missing one or more security updates.

Description :

From Red Hat Security Advisory 2013:0502 :

Updated core client packages for the X Window System that fix one
security issue, several bugs, and add various enhancements are now
available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having low
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 Core X11 clients packages provide the xorg-x11-utils,
xorg-x11-server-utils, and xorg-x11-apps clients that ship with the X
Window System.

It was found that the x11perfcomp utility included the current working
directory in its PATH environment variable. Running x11perfcomp in an
attacker-controlled directory would cause arbitrary code execution
with the privileges of the user running x11perfcomp. (CVE-2011-2504)

Also with this update, the xorg-x11-utils and xorg-x11-server-utils
packages have been upgraded to upstream version 7.5, and the
xorg-x11-apps package to upstream version 7.6, which provides a number
of bug fixes and enhancements over the previous versions. (BZ#835277,
BZ#835278, BZ#835281)

All users of xorg-x11-utils, xorg-x11-server-utils, and xorg-x11-apps
are advised to upgrade to these updated packages, which fix these
issues and add these enhancements.
