Florian Weimer of Red Hat Product Security discovered that libvdpau, the VDPAU wrapper library, did not properly validate environment variables, allowing local attackers to gain additional privileges.

For Debian 6 ‘Squeeze’, these problems have been fixed in libvdpau version 0.4.1-2+deb6u1. See DSA 3355-1 for information on other Debian releases.

We recommend that you upgrade your libvdpau packages.
