Proprietary Nvidia Linux Driver Contains Privilege Escalation Hole
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.
I'd like to say that this would not have happened with an open source driver, but that's not necessarily true. It would almost definitely have been patched by now though.
Maybe people need to stop being apologists for this kind of thing...
Companies don't just hand out the email address for the head of their SW development division; maybe if they did we could them let the right people know. I emailed a random Joe when I found an issue with a site, and it got escalated up and it got fixed.
Maybe if Nvidia had better quality random Joe's, when this sort of stuff did pass by them it would get escalated and not deleted.
The graphics driver is both monstrously large and operates at a very low level, there are going to be tons and tons of security problems with it when people start seriously looking at it. As John Carmak put it: I agree with Microsoft’s assessment that WebGL is a severe security risk. The gfx driver culture is not the culture of security.
I read the internet for the articles.
Somebody should probably tell Nvidia that a driver that enables arbitrary memory read/write could probably be used as a DRM circumvention mechanism if targeted at a 'protected' program rather than the kernel. That might actually get them to fix it...
Use Windows and you don't get linux malware. True story, mod +5 true accordingly.
Since Nvidia's drivers share a large amount of common code, I'd say it's only a matter of time.
Correct. That's why i choose AMD.
Not that they're that much better, but at least they tried to.
When are we going to get all the software available prepackaged and regularly updated from the repository?
That's a fairly half-hearted troll. Most Linux distros have package management and multi-source software repositories that make iOS, Metro, and OS X look like the limited attempts at platform lock-in that they really are.
