Dist Redhat Esm H88
Essential kernel update for CentOS Linux includes vital security patches to guard against possible vulnerabilities.
Updated kernel packages that fix one security issue are now available for Red Hat Enterprise Linux 6

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/kb/docs/DOC-11259

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.
This update fixes the following security issue:
* A use-after-free flaw was found in the Linux kernel's RPC server sockets implementation. A remote attacker could use this flaw to trigger a denial of service by sending a corrupted packet to a target system. (CVE-2011-0714, Important)
Red Hat would like to thank Adam Prince for reporting this issue.
Users should upgrade to these updated packages, which contain a backported patch to correct this issue. The system must be rebooted for this update to take effect.
