Oh, this is a nice one:

Security vunerabilities in Nvidia binary drivers.

With active proof-of-concept exploit for Linux. This is not only a local vunerability with X + nvidia drivers, but it can be remotely exploitable.. for instance if your browsing to a malicious website it's possible for somebody to have your browser display something _which_could_give_them_root_access_.

This is a problem with how Nvidia accelerates rendering of text. This is a very very serious problem.

This bug has been around for years now. First reported in 2004 it took nearly 2 years for Nvidia to aknowledge the problem, which was in July 2006 and they still haven't fixed it.

To me this is headlines-style stuff.

There is more information on the security exploit over @ Kernel Trap (http://kerneltrap.org/node/7228)

The bug may be fixed in NVIDIA Beta 1.0-9625.

For 1.0-8XXX series, the exploit can be fixed by throwing:

Option "RenderAccel" "False"

into the xorg.conf

NVIDIA has released a statement on the matter:

The drivers at http://www.nvidia.com/object/unix.html now also contain a hotfix.
