xfree86-glx-integer-dos (15273) The risk level is classified as MediumMedium Risk

Description:

XFree86 is vulnerable to a denial of service, caused by integer signedness errors. By using the GLX extension and Direct Rendering Infrastructure, a local or remote attacker could cause the X Server to crash, and possibly gain root privileges on the system.


Consequences:

Denial of Service

Remedy:

For Debian GNU/Linux 3.0 (woody):
Upgrade to the latest xfree86 package (4.1.0-16woody3 or later), as listed in DSA-443-1. See References.
