Detail

Problem 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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64

3. Description:

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.

4. Solution:

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/FAQ_58_10188

5. Bugs fixed (http://bugzilla.redhat.com/):

391841 - CVE-2007-5958 Xorg / XFree86 file existence disclosure vulnerability 413721 - CVE-2007-6429 xorg / xfree86: integer overflow in EVI extension 413741 - CVE-2007-6429 xorg / xfree86: integer overflow in MIT-SHM extension 413791 - CVE-2007-6428 xorg / xfree86: information disclosure via TOG-CUP extension 413811 - CVE-2007-6427 xorg / xfree86: memory corruption via XInput extension 414031 - CVE-2007-5760 xorg: invalid array indexing in XFree86-Misc extension
