libvdpau - security update

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.
