If you still have the popular open-source VLC media player installed on your computer, you might want to uninstall it temporarily. A critical security flaw was recently discovered by German security agency CERT-Bund, and VideoLAN doesn’t have a complete patch at the moment.
The security flaw allows for remote code execution (RCE), which gives hackers total access to your computer to install, run, and modify anything on it without your knowledge. Additionally, hackers can exploit the issue to cause denial-of-service attacks, which is a common function of certain malware. CERT-Bund has given this a base vulnerability score of 9.8 out of 10.
