Updated XFree86 packages that fix a minor denial of service vulnerability are now available.
XFree86 is an implementation of the X Window System, providing the core graphical user interface and video drivers. Flaws in XFree86 4.1.0 allows local or remote attackers who are able to connect to the X server to cause a denial of service via an out-of-bounds array index or integer signedness error when using the GLX extension and Direct Rendering Infrastructure (DRI). The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2004-0093 and CAN-2004-0094 to these issues. These issues do not affect CentOS Linux 3. All users of XFree86 are advised to upgrade to these erratum packages, which contain a backported fix and are not vulnerable to these issues.
