Fedora Core 1 : XFree86-4.3.0-55 (2004-069)
Critical Nessus Plugin ID 13677
SynopsisThe remote Fedora Core host is missing a security update.
DescriptionUpdated XFree86 packages that fix a privilege escalation vulnerability are now 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 CVE-2004-0083 and CVE-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 CVE-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.
Red Hat would like to thank David Dawes from XFree86 for the patches and notification of these issues.
Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
