Description :

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.

Solution :

Upgrade to :
- linux-doc-2.6.8.1-2.6.8.1-16.4 (Ubuntu 4.10)
- linux-headers-2.6.8.1-4-2.6.8.1-16.4 (Ubuntu 4.10)

- linux-headers-2.6.8.1-4-686-2.6.8.1-16.4 (Ubuntu 4.10)
- linux-headers-2.6.8.1-4-686-smp-2.6.8.1-16.4 (Ubuntu 4.10)
- linux-headers-2.6.8.1-4-amd64-generic-2.6.8.1-16.4 (Ubuntu 4.10)
