Insight

Insight

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: 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
