Synopsis :

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

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 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.
