Package        : libvdpau
Debian Bug     : 802625

The previous update for libvdpau, DSA-3355-1, introduced a regression in
the stable distribution (jessie) causing a segmentation fault when the
DRI_PRIME environment variable is set. For reference, the original
advisory text follows.

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 the stable distribution (jessie), this problem has been fixed in
version 0.8-3+deb8u2.

We recommend that you upgrade your libvdpau packages.
