CentOS Update for rtkit CESA-2013:1282 centos6

Published: 2013-10-03 04:48:34
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:L/AC:L/Au:N/C:P/I:P/A:P

Affected Versions:
rtkit on CentOS 6

Technical Details:
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 Linux Distribution Package, which contains a backported patch to correct this issue.

Recommendations:
Please install the updated Linux Distribution Packages.

Detection Type:
Linux Distribution Package

Solution Type:
Vendor Patch

Summary:
The remote host is missing an update for the 'rtkit' Linux Distribution Package(s) announced via the referenced advisory.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
