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.
