Description Florian Weimer 2015-08-14 19:40:12 UTC 
It was discovered that libvdpau incorrectly checks if the process underwent a security transition at startup, related to processing of the VDPAU_DRIVER_PATH environment variable.  This may allow local attackers gain additional privileges.

Acknowledgements:

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

I am doing some janitor tasks on my bugzillas. Can we close this one? It seemed to have been fixed 6 years ago...
