CentOS Errata and Security Advisory CESA-2013:1282
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
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. (CVE-2013-4326)
All rtkit users are advised to upgrade to this updated package, which
contains a backported patch to correct this issue.
