![]() Once that’s done, go to “ Settings.” This will be the small gear icon on the top right of the screen beside your username. If it’s been a while since you used the GeForce Experience, or if you’ve never used it, you might have to adjust the settings and optimize the program before enabling ShadowPlay.įirst, make sure the software itself is up-to-date and then download and install new drivers, if there are any. You can find the download link on NVIDIA’s website. ![]() If you don’t have it on your computer, you will first need to download and install it. If you have the software, click on it to start it. This Nvidia software helps you do many things, like optimizing the game settings and downloading and installing the latest drivers. You can access Nvidia ShadowPlay only through the GeForce Experience. To enable ShadowPlay, here’s what you need to do: Step #1: Open GeForce Experience Plus, it works even on Windows 7! How To Enable ShadowPlay You most likely have this feature if you have the latest NVIDIA graphics card. It is also an in-game overlay that will enable you to check your fps and take screenshots. Vulnerability experts Michiel Prins, co-founder of webinar sponsor HackerOne, and Greg Ose, GitHub’s application security engineering manager, join Threatpost editor Tom Spring to discuss what vulnerability types are most common in today’s software, and what kind of impact they would have on organizations if exploited.Nvidia ShadowPlay (now named Nvidia Share but still popularly known as ShadowPlay) is a tool that allows you to both record and stream live gameplay. Two information disclosure bugs, rated high severity, were also patched by NVIDIA.ĭon’t miss the free replay of our Threatpost webinar, “Exploring the Top 15 Most Common Vulnerabilities with HackerOne and GitHub.” Versions of GeForce Experience for Windows before 3.18 are impacted users can update to 3.18 to fix the flaw.Įarlier in March, Google issued patches for bugs in NVIDIA components used in Android handsets. Often, this just means you can cause a denial of service by overwriting critical system files, but if you can control the data that is being written in some way, often you can do more with it.”įor instance, some files could be polluted with commands that write a file to the system startup folder, leading to commands being executed by other users at startup. He added, “Essentially, with an arbitrary file write, you can force an application to overwrite any file on the system as a privileged user. “The issue here is that everyone could modify the file in any way, this includes creating hard or symbolic links to other files on the system,” Yesland said. Thus, it’s possible for a low-privileged user to create a symbolic link (a special kind of file that points to another file) between log files and any other system file that in turn allows the user to overwrite the contents of that system file. When inspecting the permissions on the files for the affected features, Yesland realized that anyone can have control over them. The issue was reported by David Yesland of Rhino Security Labs, who published a proof-of-concept exploit for the vulnerability. “This behavior may lead to code execution, denial-of-service or escalation of privileges.” ![]() “When opening a file, the software does not check for hard links,” said Nvidia in a Tuesday security update. ![]() GeForce Experience is installed by default on systems running NVIDIA GeForce products, Nvidia’s brand of GPUs.Įssentially, the flaw allows any system file within the application to be overwritten when ShadowPlay (Nvidia’s game-play recording feature), NvContainer (Nvidia’s contain runtime process), or GameStream (Nvidia’s game-streaming feature) are enabled. GeForce Experience is a supplemental application to the GeForce GTX graphics card - it keeps users’ drivers up-to-date, automatically optimizes their game settings and more. The vulnerability (CVE‑2019‑5674) has a CVSS score of 8.8, making it high severity. Nvidia, a maker of gaming-friendly graphics processing units (GPU), has patched a high-severity vulnerability in its GeForce Experience software, which could lead to code execution or denial-of-service of products if exploited. ![]()
