As an exploit for this issue in the wild, this advisory was sent out without
builds for the IBM S/390, Motorola 680x0 and HP Precision architectures being
available. They will be released in a followup-advisory as soon as they
are available. Also, the kernels for the FAI installer haven't been updated
yet. As a workaround we recommend to mount proc with the nosuid and noexec
options.

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.

Upgrade...
