Red Hat Security Advisory 2013-1282-01
Posted Sep 24, 2013
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2013-1282-01 - RealtimeKit is a D-Bus system service that changes the scheduling policy of user processes/threads to SCHED_RR on request. It is intended to be used as a secure mechanism to allow real-time scheduling to be used by normal user processes. It was found that RealtimeKit communicated with PolicyKit for authorization using a D-Bus API that is vulnerable to a race condition. This could have led to intended PolicyKit authorizations being bypassed. This update modifies RealtimeKit to communicate with PolicyKit via a different API that is not vulnerable to the race condition.

3. Description:

RealtimeKit is a D-Bus system service that changes the scheduling policy of
user processes/threads to SCHED_RR (that is, realtime scheduling mode) on

led to intended PolicyKit authorizations being bypassed. This update
modifies RealtimeKit to communicate with PolicyKit via a different API that
is not vulnerable to the race condition. (CVE-2013-4326)
