RHSA-2007:0157 - Security Advisory

Topic

Updated xorg-x11-apps and libX11 packages that fix a security issue are now
available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

Description

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 flaw was found in the X.org XGetPixel() function.
Improper use of this function could cause an application calling it to
function improperly, possibly leading to a crash or arbitrary code
execution. (CVE-2007-1667)

Users of the X.org X11 server should upgrade to these updated packages,
which contain a backported patch and are not vulnerable to this issue.
