RHEL 5 : xorg-x11-server (RHSA-2008:0031)

High Nessus Plugin ID 30003

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated xorg-x11-server packages that fix several security issues are now available for Red Hat Enterprise Linux 5.

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.

X.Org is an open source implementation of the X Window System. It provides 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 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)

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-server should upgrade to these updated packages, which contain backported patches to resolve these issues.
