An anonymous reader writes "The Nvidia binary driver has been exploited by an anonymous hacker, who reported it to nvidia months ago and it was never fixed. Now the exploit was made public."
The one releasing the exploit (relayed to him anonymously) is David Arlie
, well known X hacker. The bug lets the attacker write to any part of memory on the system by shifting the VGA window; the attached exploit uses this to attain superuser privileges. It appears that this has been known to Nvidia for at least a month.
