Description Florian Weimer 2015-08-14 15:46:40 EDT

It was discovered that libvdpau does not guard against directory traversal while processing the VDPAU_DRIVER environment variable.  This may allow local attackers gain additional privileges.

Acknowledgements:

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