Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated kernel packages that fix one security issue and one bug are now available for Red Hat Enterprise Linux 6.3 Extended Update Support.

The Red Hat Security Response Team 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 flaw was found in the way the Linux kernel processed an authenticated COOKIE_ECHO chunk during the initialization of an SCTP connection. A remote attacker could use this flaw to crash the system by initiating a specially crafted SCTP handshake in order to trigger a NULL pointer dereference on the system. (CVE-2014-0101, Important)

Red Hat would like to thank Nokia Siemens Networks for reporting this issue.

This update also fixes the following bug :

* Due to an incorrect call of the weak-modules script in the kernel spec file, the weak-modules directory was removed from the system when removing or upgrading certain kernel packages related to weak-modules, such as kernel-debug. With this update, the weak-modules call in the kernel spec file has been corrected, and the script now preserves the weak-modules directory on the system in this scenario. (BZ#1076599)

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

Solution

Update the affected packages.
