The entire conflict here is that norms about what's considered responsible were developed in a different context, where vulnerability reports were generated at a much lower rate and dedicated CVE-searching teams were much less common. FFmpeg says this was "AI generated bug reports on an obscure 1990s hobby codec"; if that's accurate (I have no reason to doubt it, just no time to go check), I tend to agree that it doesn't make sense to apply the standards that were developed for vulnerabilities like "malicious PNG file crashes the computer when loaded".

The codec is compiled in, enabled by default, and auto detected through file magic, so the fact that it is an obscure 1990s hobby codec does not in any way make the vulnerability less exploitable. At this point I think FFmpeg is being intentionally deceptive by constantly mentioning only the ancient obscure hobby status and not the fact that it’s on by default and autodetected. They have also rejected suggestions to turn obscure hobby codecs off by default, giving more priority to their goal of playing every media format ever than to security.

Yeah, ffmpeg's responses is really giving me a disingenuous vibe as their argument is completely misleading (and it seems to be working on a decent amount of people who don't try to read further into it). IMO it really damages their reputation in my eyes. If they handled it maturely I think I would have had a bit more respect for them.

As a user this is making me wary of running it tbh.

I think the discussion on what standard practice should be does need to be had. This seems to be throwing blame at people following the current standard.

If the obscure coded is not included by default or cannot be triggered by any means other than being explicitly asked for, then it would be reasonable to tag it Won't Fix. If it can be triggered by other means, such as auto file type detection on a renamed file, then it doesn't matter how obscure the feature is, the exploit would affect all.

What is the alternative to a time limited embargo. I don't particularly like the idea of groups of people having exploits that they have known about for ages that haven't been publicly disclosed. That is the kind of information that finds itself in the wrong hands.

Of course companies should financially support the developers of the software they depend upon. Many do this for OSS in the form of having a paid employee that works on the project.

Specifically, FFMPEG seems to have a problem that much of their limitation of resources comes from them alienating contributors. This isn't isolated to just this bug report.

FFMPEG does autodetection of what is inside a file, the extension doesn't really matter. So it's trivial to construct a video file that's labelled .mp4 but is really using the vulnerable codec and triggers its payload upon playing it. (Given ffmpeg is also used to generate thumbnails in Windows if installed, IIRC, just having a trapped video file in a directory could be dangerous.)

> CVE-searching teams

Silly nitpick, but you search for vulnerabilities not CVEs. CVE is something that may or may not be assigned to track a vulnerability after it has been discovered.

Most security issues probably get patched without a CVE ever being issued.

It is accurate. This is a codec that was added for archival and digital preservation purposes. It’s like adding a Unicode block for some obscure 4000 year old dead language that we have a scant half dozen examples of writing.
