Description Florian Weimer 2015-08-14 19:49:05 UTC

It was discovered that the trace functionality of libvdpau can be used to overwrite arbitrary files if the process underwent a trust transition at startup.  This may allow local attackers gain additional privileges.

Acknowledgements:

This issue was discovered by Florian Weimer of Red Hat Product Security.
