From Red Hat Security Advisory 2010:0661 :
Updated kernel packages that fix one security issue are now available for Red Hat Enterprise Linux 5.
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.
This update fixes the following security issue :
Red Hat would like to thank the X.Org security team for reporting this issue. Upstream acknowledges Rafal Wojtczuk as the original reporter.
Users should upgrade to these updated packages, which contain backported patches to correct this issue. The system must be rebooted for this update to take effect.

Updated kernel packages that fix one security issue are now available

The Red Hat Security Response Team has rated this update as having

(CVSS) base score, which gives a detailed severity rating, is

The kernel packages contain the Linux kernel, the core of any Linux
operating system.
This update fixes the following security issue :
* when an application has a stack overflow, the stack could silently
overwrite another memory mapped area instead of a segmentation fault
occurring, which could cause an application to execute arbitrary code,
possibly leading to privilege escalation. It is known that the X
Window System server can be used to trigger this flaw. (CVE-2010-2240,
Important)
