Subject: Security ERRATA Important: kernel on SL5.x i386/x86_64
Newsgroups: gmane.linux.scientific.errata
Date: Thursday 31st May 2012 18:50:04 UTC (over 4 years ago)
Synopsis:    Important: kernel security and bug fix update
Issue Date:  2012-05-29
CVE Numbers: CVE-2012-2136


The kernel packages contain the Linux kernel, the core of any Linux
operating system.

This update fixes the following security issue:

* It was found that the data_len parameter of the sock_alloc_send_pskb()
function in the Linux kernel's networking implementation was not validated
before use. A local user with access to a TUN/TAP virtual interface could
use this flaw to crash the system or, potentially, escalate their
privileges. Note that unprivileged users cannot access TUN/TAP devices
until the root user grants them access. (CVE-2012-2136, Important)

We have also posted updated kernel-module-* packages corresponding to
this kernel version.

The system must be rebooted for this update to take effect.
