Bug#289155: CAN-2004-1235: uselib() privilege escalation

[Moritz Muehlenhoff <jmm@inutil.org>]

Package: kernel-source-2.6.8
Version: 2.6.8
Severity: grave
Tags: security
Justification: user security hole

Paul Starzetz from iSec Security Research has discovered a local root exploit in
the Linux kernel:
> Locally exploitable  flaws have  been  found in  the  Linux
> binary format loaders' uselib() functions that allow  local
> users to gain root privileges.

I haven't found a patch for 2.6 yet, a patch for 2.4 is available in
the 2.4 Bitkeeper branch.

Cheers,
        Moritz
