Detailed Explanation for this Vulnerability Assessment

The remote host is missing the patch for the advisory FEDORA-2004-069 (XFree86).

XFree86 is an open source implementation of the X Window System. It
provides the basic low level functionality which full fledged
graphical user interfaces (GUIs) such as GNOME and KDE are designed
upon.

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 rights.
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.
