New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote CentOS host is missing one or more security updates.
DescriptionUpdated 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 CVE-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 :
- The 'radeon' driver has been modified to disable 'RENDER' acceleration by default, due to a bug in the implementation which has not yet been isolated. This can be manually re-enabled by using the following option in the device section of the X server config file :
- The 'vmware' video driver is now available on 64-bit AMD64 and compatible systems.
- The Intel 'i810' video driver is now available on 64-bit EM64T systems.
- Stability fixes in the X Server's PCI handling layer for 64-bit systems, which resolve some issues reported by 'vesa' and 'nv' driver users.
- Support for Hewlett Packard's Itanium ZX2 chipset.
- Nvidia 'nv' video driver update provides support for some of the newer Nvidia chipsets, as well as many stability and reliability fixes.
- Intel i810 video driver stability update, which fixes the widely reported i810/i815 screen refresh issues many have experienced.
- Packaging fixes for multilib systems, which permit both 32-bit and 64-bit X11 development environments to be simultaneously installed without file conflicts.
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.
SolutionUpdate the affected xorg-x11 packages.
