CESA-2004:061: XFree86 security update
Description
Updated XFree86 packages that fix a privilege escalation vulnerability are now available. [Update 16 February 2004] Erratum filelist has been modified for x86_64 and s390x only so that the correct multi-lib packages are available.
XFree86 is an implementation of the X Window System, providing the core graphical user interface and video drivers. iDefense discovered two buffer overflows in the parsing of the 'font.alias' file. A local attacker could exploit this vulnerability by creating a carefully-crafted file and gaining root privileges. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2004-0083 and CAN-2004-0084 to these issues. Additionally David Dawes discovered additional flaws in reading font files. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0106 to these issues. All users of XFree86 are advised to upgrade to these erratum packages, which contain a backported fix and are not vulnerable to these issues. CentOS would like to thank David Dawes from XFree86 for the patches and notification of these issues.
