1. Topic:
A vulnerability has been found in the ptrace code of the kernel (ptrace is
the part that allows program debuggers to run) that could be abused by
local users to gain root privileges.

3. Problem description:
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
The procedure for upgrading the kernel is documented at:
http://www.redhat.com/support/docs/howto/kernel-upgrade/kernel-upgrade.html
Please read the directions for your architecture carefully before
proceeding with the kernel upgrade.
Please note that this update is also available via Red Hat Network. Many
people find this to be an easier way to apply updates. To use Red Hat
Network, launch the Red Hat Update Agent with the following command:
up2date
This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system. Note that you need to select the kernel
explicitly on default configurations of up2date.
