New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 7.4
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated kernel packages that fix one security issue and one bug are now available for Red Hat Enterprise Linux 6.2 Advanced Update Support.
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.
The kernel packages contain the Linux kernel, the core of any Linux operating system.
* A flaw was found in the way the pppol2tp_setsockopt() and pppol2tp_getsockopt() functions in the Linux kernel's PPP over L2TP implementation handled requests with a non-SOL_PPPOL2TP socket option level. A local, unprivileged user could use this flaw to escalate their privileges on the system. (CVE-2014-4943, Important)
Red Hat would like to thank Sasha Levin for reporting this issue.
This update also fixes the following bug :
* When a device was registered to a bus, a race condition could occur between the device being added to the list of devices of the bus and binding the device to a driver. As a result, the device could already be bound to a driver which led to a warning and incorrect reference counting, and consequently to a kernel panic on device removal. To avoid the race condition, this update adds a check to identify an already bound device. (BZ#1114409)
All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.
SolutionUpdate the affected packages.
