Hi Joseph - thanks for the report. We are aware of this CVE and have triaged it in the Ubuntu CVE Tracker:

  https://people.canonical.com/~ubuntu-security/cve/2016/CVE-2016-7953.html

We have it rated as a 'low' which means that it will not be fixed in our stable Ubuntu releases unless there's a medium or higher issue found against libxvmc. This is to minimize regression risks for low impact security issues.

Is this going to get pulled into Artful? It's been in Debian since Dec 5, 2016. It made it into Debian 9.

  * Bump debhelper compat to 10.
  * Switch from xsfbs to dh.
  * Drop unneeded libtool and automake build-deps, debhelper now depends
    on and calls dh-autoreconf for us.
  * Switch to -dbgsym packages.
  * Move XvMCConfig to its target directory with libxvmc1.install.
  * Bump Standards-Version to 3.9.8, no changes.
