[USN-39-1] Linux amd64 kernel vulnerability

===========================================================
Ubuntu Security Notice USN-39-1           December 16, 2004
linux-source-2.6.8.1 vulnerability
CAN-2004-1074, USN-30-1
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

linux-image-2.6.8.1-4-amd64-generic
linux-image-2.6.8.1-4-amd64-k8
linux-image-2.6.8.1-4-amd64-k8-smp
linux-image-2.6.8.1-4-amd64-xeon

The problem can be corrected by upgrading the affected package to
version 2.6.8.1-16.4.  You need to reboot the computer after
performing a standard system upgrade to effect the necessary changes.

Details follow:

USN-30-1 fixed several flaws in the Linux ELF binary loader's handling
of setuid binaries. Unfortunately it was found that these patches were
not sufficient to prevent all possible attacks on 64-bit platforms, so
previous amd64 kernel images were still vulnerable to root privilege
escalation if setuid binaries were run under certain conditions.

This issue does not affect the i386 and powerpc platforms.
