Ubuntu 4.10 : linux-source-2.6.8.1 vulnerability (USN-39-1)

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
