The remote Red Hat host is missing one or more security updates.
An updated rtkit package that fixes one security issue is now
available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System
(CVSS) base score, which gives a detailed severity rating, is
available from the CVE link in the References section.
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
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
All rtkit users are advised to upgrade to this updated package, which
contains a backported patch to correct this issue.
