Synopsis

The remote CentOS host is missing one or more security updates.

Description

Updated xorg-x11 packages that fix several security issues are now available for Red Hat Enterprise Linux 4.

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

[Updated 18th January 2008] The original packages distributed with this errata had a bug which could cause some X applications to fail on 32-bit platforms. We have updated the packages to correct this bug.

The xorg-x11 packages contain X.Org, 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.

Two integer overflow flaws were found in the X.Org server's EVI and MIT-SHM modules. A malicious authorized client could exploit these issues to cause a denial of service (crash), or potentially execute arbitrary code with root privileges on the X.Org server.
(CVE-2007-6429)

A heap based buffer overflow flaw was found in the way the X.Org server handled malformed font files. A malicious local user could exploit these issues to potentially execute arbitrary code with the privileges of the X.Org server. (CVE-2008-0006)

A memory corruption flaw was found in the X.Org server's XInput extension. A malicious authorized client could exploit this issue to cause a denial of service (crash), or potentially execute arbitrary code with root privileges on the X.Org server. (CVE-2007-6427)

An input validation flaw was found in the X.Org server's XFree86-Misc extension. A malicious authorized client could exploit this issue to cause a denial of service (crash), or potentially execute arbitrary code with root privileges on the X.Org server. (CVE-2007-5760)

An information disclosure flaw was found in the X.Org server's TOG-CUP extension. A malicious authorized client could exploit this issue to cause a denial of service (crash), or potentially view arbitrary memory content within the X server's address space. (CVE-2007-6428)

An integer and heap overflow flaw were found in the X.Org font server, xfs. A user with the ability to connect to the font server could have been able to cause a denial of service (crash), or potentially execute arbitrary code with the permissions of the font server.
(CVE-2007-4568, CVE-2007-4990)

A flaw was found in the X.Org server's XC-SECURITY extension, that could have allowed a local user to verify the existence of an arbitrary file, even in directories that are not normally accessible to that user. (CVE-2007-5958)

Users of xorg-x11 should upgrade to these updated packages, which contain backported patches to resolve these issues.

Solution

Update the affected xorg-x11 packages.
