XFree86 is an implementation of the X Window System, which provides the
core functionality for the Linux graphical desktop.
An integer overflow flaw in the way the XFree86 server processes PCF files
was discovered. A malicious authorized client could exploit this issue to
cause a denial of service (crash) or potentially execute arbitrary code
with root privileges on the XFree86 server. (CVE-2006-3467)
Users of XFree86 should upgrade to these updated packages, which contain a
backported patch and is not vulnerable to this issue.
