Note: Versions mentioned in the description apply only to the upstream rtkit package and not the rtkit package as distributed by Ubuntu. See How to fix? for Ubuntu:13.04 relevant fixed versions and status.

RealtimeKit (aka rtkit) 0.5 does not properly use D-Bus for communication with a polkit authority, which allows local users to bypass intended access restrictions by leveraging a PolkitUnixProcess PolkitSubject race condition via a (1) setuid process or (2) pkexec process, a related issue to CVE-2013-4288.
