"Updated kernel packages that fix one security issue, several bugs, and
add one enhancement are now available for Red Hat Enterprise Linux 6.5
Extended Update Support.

Red Hat Product Security 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 NULL pointer dereference flaw was found in the way the Linux
kernel's Stream Control Transmission Protocol (SCTP) implementation
handled simultaneous connections between the same hosts. A remote
attacker could use this flaw to crash the system. (CVE-2014-5077,
Important)

This update also fixes several bugs and adds one enhancement.
Documentation for these changes is available from the Technical Notes
document linked to in the References section.

All kernel users are advised to upgrade to these updated packages,
which contain backported patches to correct these issues and add this
enhancement. The system must be rebooted for this update to take
effect."
