CVE-2013-2141

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.8.9

Description The issue allows local users to obtain sensitive information from kernel memory. This is due to the do tkill function in kernel/signal.c not initializing a certain data structure, which can be exploited via a crafted application that makes a (1) tkill or (2) tgkill system call.

Recommendations For Linux kernel versions prior to 3.8.9, update to version 3.8.9 or later to resolve the issue. As a temporary workaround, consider restricting access to the tkill and tgkill system calls to minimize the risk of exploitation.
