Title:	CentOS Update for rtkit CESA-2013:1282 centos6
Summary:	The remote host is missing an update for the 'rtkit'; package(s) announced via the referenced advisory.
Description:	Summary: The remote host is missing an update for the 'rtkit' package(s) announced via the referenced advisory. Vulnerability Insight: 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. Affected Software/OS: rtkit on CentOS 6 Solution: Please install the updated packages. CVSS Score: 4.6 CVSS Vector: AV:L/AC:L/Au:N/C:P/I:P/A:P
