Scientific Linux Security Update : kernel on SL6.x i386/x86_64
High Nessus Plugin ID 66490
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionThis update fixes the following security issue :
- It was found that the Scientific Linux 6.1 kernel update (SLSA-2011:0542) introduced an integer conversion issue in the Linux kernel's Performance Events implementation.
This led to a user-supplied index into the perf_swevent_enabled array not being validated properly, resulting in out-of-bounds kernel memory access. A local, unprivileged user could use this flaw to escalate their privileges. (CVE-2013-2094, Important)
A public exploit that affects Scientific Linux 6 is available.
Refer to Red Hat Knowledge Solution 373743 for further information and mitigation instructions for users who are unable to immediately apply this update.
The system must be rebooted for this update to take effect.
SolutionUpdate the affected packages.
