GeForce 384.94 drivers bring a bevy of security fixes

As it turns out, owners of Nvidia graphics cards have greater reasons to update their drivers than just getting optimizations for ARK: Survival Evolved. Nvidia has released a security bulletin detailing multiple vulnerabilities in its display drivers, and advises users to update the software to version 384.94.

The problems were present in the kernel mode layer of the GPU display driver. Brought to Nvidia's attention by Andrei Lasu and Alastair Donaldson of Imperial College London, the vulnerabilities could be exploited to stop the drivers from working or to potentially gain access to user data. The bugs include a missing user permissions check, a null pointer dereference, and multiple problems in the handler for the DirectX DxgkDdiEscape interface. Google's Project Zero team brought to light some issues with Nvidia's usage of this interface back in February, noting that it was vulnerable to a variety of attacks.

The security issues affect Nvidia's drivers across all operating systems. For most users, fixes are already available. Owners of GeForce cards using Windows should grab driver version 384.94, released yesterday. Linux users probably already have the necessary fixes in place, as they were included as early as driver version 375.82 for some users, and in version 384.59 for others. Users of Nvidia's Quadro and Tesla products will have to hang tight, as Nvidia hasn't yet released a fixed driver for these cards. Whatever Nvidia product you might have, it's a good time to check what driver version you're using and update as needed.

    AAAAAAAArgh! Couldn’t they find those security issues two months earlier? I might have successfully defend my master thesis with this as reference…

    432MB seems like a huge jump in size. Last GeForce driver I installed was probably around 350MB or so.

      Not sure what you are talking about as around 430 mb has been the norm for a while.

        Guess it’s been a while since I updated the GPU drivers

    For those interested, the ARK improvements are perceptible.

    I’m up about 5FPS at exact same settings as on 382s.

    Local texture streaming also seems improved, at the expense of a little distance – althought this may be bias.

    thanks for letting us know. I never update drivers unless I am looking for a bug fix.

    I’m glad to see display drivers coming under more scrutiny, particularly now that they are more directly exposed to the web via WebGL. Unfortunately I expect to see a lot more blatant security holes come to light in this area in the future (in both hardware and software), but at least we’re starting to move in the right direction now.

    [quote<]The security issues affect Nvidia's drivers across all operating systems. [/quote<] Well it's nice to see that security bugs are finally taking cross-platform compatibility seriously.

    Seems like the driver was asleep at the wheel.

      And even a get-away driver for any crime is culpable for the crime…
