I feel as though this should be googlebrotli2shell, not http2shell. Google deserves to take a bit of a reputational hit for this. This is a basic memory safety violation, from the same organization that does wuffs, that promotes Rust for memory safety, that has Carbon. zstd has high quality rust implementations and is from roughly the same time.

On top of that, the brotli library saw no releases for almost a full year, with the fix for this vulnerability being committed back in February. Google builds from main for all their projects, so were unaffected, but open source releases are a complete afterthought. Over 100 commits with miscellaneous fixes left languishing until a security incident forces a release.
