There is mention of a critical security flaw

I checked

and saw the following comments

If you land on this ticket through a news article claiming a critical flaw in VLC, I suggest you to read the above comment first and reconsider your (fake) news sources.


the previous comment is

This does not crash a normal release of VLC 3.0.7.1

Can we get clarification on this since this comes from German security agency CERT-Bund

Thanks

I question why any video player need remote code execution
(Arbitratry) remote code execution is a flaw where someone is able to write and execute any code in a software through a network trigger. In this case, it would be triggering a write of code payload in an executable area of memory executed by VLC , through buffer write overflow and function pointer call. https://en.wikipedia.org/wiki/Arbitrary_code_execution
Media player like VLC doesn't need RCE, it's a bug when they exists.

Here, even with obsolete dependencies, there is no remote code execution exploit currently.
