According to TechPowerUp, AMD Adrenalin 20.1.1 drivers fix four major safety gaps in Radeon graphics cards. Interestingly, the list of changes on manufacturer's official website doesn't mention a word about this extremely important fact. These vulnerabilities have been catalogued by Talos Intelligence as CVE-2019-5124, CVE-2019-5146, CVE-2019-5147 and CVE-2019-5183. They exploit the weakness of the ATIDXX64.dll library, exposing Radeon-using computers to DoS and RCE attacks.
The case is all the more serious as attacks using these vulnerabilities can also be carried out from the level of a virtual machine (tested on VMWare), as well as through a website (using WebGL technology). Radeon owners are advised to download and install software version 20.1.1 as soon as possible to avoid unnecessary risks. The latest drivers can be found on AMD's official website in the support section.
