Red Hat Enterprise Linux 5: RHSA-2013:1348-01 Moderate: Kernel DoS Issue

Recent kernel updates bolster security, refine functionalities, and address multiple issues for CentOS Linux 7.

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.
This update fixes the following security issue:
* It was found that a deadlock could occur in the Out of Memory (OOM) killer. A process could trigger this deadlock by consuming a large amount of memory, and then causing request_module() to be called. A local, unprivileged user could use this flaw to cause a denial of service (excessive memory consumption). (CVE-2012-4398, Moderate)
Red Hat would like to thank Tetsuo Handa for reporting this issue.
This update also fixes numerous bugs and adds various enhancements. Refer to the Red Hat Enterprise Linux 5.10 Release Notes for information on the most significant of these changes, and the Technical Notes for further information, both linked to in the References.
All Red Hat Enterprise Linux 5 users are advised to install these updated packages, which correct this issue, and fix the bugs and add the enhancements noted in the Red Hat Enterprise Linux 5.10 Release Notes and Technical Notes. The system must be rebooted for this update to take effect.
