Debian Security Advisory DSA 1111-1 (kernel-source-2.6.8 et. al.) announces a race condition in the process filesystem, leading to privilege escalation. It affects various kernel versions for different architectures in Debian 3.1 (sarge), with recommendations to upgrade the kernel package immediately and reboot

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

Debian 3.1 (sarge)
Source                      2.6.8-16sarge4
Alpha architecture          2.6.8-16sarge4
AMD64 architecture          2.6.8-16sarge4
Intel IA-32 architecture    2.6.8-16sarge4
Intel IA-64 architecture    2.6.8-14sarge4
PowerPC architecture        2.6.8-12sarge4
Sun Sparc architecture      2.6.8-15sarge4

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";
