Red Hat 6.5 RHSA-2014:1668-01 Important DoS Issue: Kernel Update

red hat
Calendar Grey October 23, 2014
Dist Redhat Esm H88
Recent kernel updates for Red Hat address critical security vulnerabilities and bugs. Noteworthy improvements have been highlighted in this announcement.
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

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258

To install kernel packages manually, use "rpm -ivh [package]". Do not use "rpm -Uvh" as that will remove the running kernel binaries from your system. You may use "rpm -e" to remove old kernels after determining that the new kernel functions properly on your system.

Summary

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.
