kernel-source-2.6.8 - race condition

It was discovered that a race condition in the process filesystem can lead
to privilege escalation.

The following matrix explains which kernel version for which architecture
fixes the problem mentioned above:

The initial advisory lacked builds for the IBM S/390, Motorola 680x0 and HP
Precision architectures, which are now provided. Also, the kernels for the
FAI installer have been updated.

We recommend that you upgrade your kernel package immediately and reboot
the machine. If you have built a custom kernel from the kernel source
package, you will need to rebuild to take advantage of these fixes.
