xorg-x11 security update
Security Advisory: Moderate
Updated xorg-x11 packages that fix a security issue as well as various bugs
are now available for Red Hat Enterprise Linux 4.
This update has been rated as having moderate security impact by the Red
Hat Security Response Team.
X.Org X11 is the X Window System which provides the core functionality
of the Linux GUI desktop.
An integer overflow flaw was found in libXpm, which is used by some
applications for loading of XPM images. An attacker could create a
carefully crafted XPM file in such a way that it could cause an application
linked with libXpm to execute arbitrary code when the file was opened by a
victim. The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CAN-2005-0605 to this issue.
Since the initial release of Red Hat Enterprise Linux 4, a number of issues
have been addressed in the X.Org X11 X Window System. This erratum also
updates X11R6.8 to the latest stable point release (6.8.2), which includes
various stability and reliability fixes including (but not limited to) the
following:
Option "RenderAccel"
In addition to the above highlights, the X.Org X11 6.8.2 release has a
large number of additional stability fixes which resolve various other
issues reported since the initial release of Red Hat Enterprise Linux 4.
All users of X11 should upgrade to these updated packages, which resolve
these issues.
