Critical Nessus Plugin ID 37616


The remote FreeBSD host is missing one or more security-related updates.


A number of buffer overflows were recently discovered in XFree86, prompted by initial discoveries by iDEFENSE. These buffer overflows are present in the font alias handling. An attacker with authenticated access to a running X server may exploit these vulnerabilities to obtain root privileges on the machine running the X server.
