"Updated kernel packages that fix a security issue and a bug in the Red
Hat Enterprise Linux 5 kernel are now available.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

The Linux kernel handles the basic functions of the operating system.

These new kernel packages contain a fix for the following security
issue :

* a flaw in the signal handling on PowerPC-based systems that allowed
a local user to cause a denial of service (floating point corruption).
(CVE-2007-3107, Moderate).

In addition to the security issue described above, a fix for the
following have been included :

* a bug that can lead to data corruption with ServerWorks IDE
controllers.

Red Hat Enterprise Linux 5 users are advised to upgrade to these
packages, which contain backported patches to correct these issues."
