Red Hat 6.4 RHSA-2014:0432-01 Important Security Advisory: Kernel Crash

red hat
Calendar Grey April 24, 2014
Dist Redhat Esm H88
Oracle announces patch for Java SE addressing severe vulnerabilities and optimization flaws. Installation suggested.
Updated kernel packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 6.4 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/site/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 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 several bugs. Documentation for these changes will be available shortly 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. The system must be rebooted for this update to take effect.
