If you have a graphics card from Nvidia, you should immediately update the complementary program Geforce Experience to the latest version.
The reason is that versions older than 3.18 have a serious security flaw that can be used to run malicious code or perform so-called denial of service attacks, reports Zdnet.
The vulnerability was discovered by David Yesland at Rhino Security Labs and has been designated CVE‑2019‑5674. A detailed description can be read here.
In this context, it can be mentioned that Nvidia recently closed a large number of security flaws in its drivers, so you should make sure to update these as well.
