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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64
Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64
Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64

3. Description:

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.
