Scientific Linux Security Update : kernel on SL5.x i386/x86_64

This script is Copyright (C) 2012 Tenable Network Security, Inc.

Synopsis :

The remote Scientific Linux host is missing one or more security

Description :

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.
