We are cutting the release cycle short and will release curl 8.4.0 on October 11, including a fix for a severity HIGH CVE. Buckle up.

... But this time actually the worst security problem found in curl in a long time

Who also guesses buffer overflow or use-after-free?

Buffer overflows are like Lupus in House M.D.

It’s not overflow. It’s never overflow.

Why don't they just rewrite it in rust? It would be much safer right?

[–] unquietwiki 16 points 1 year ago

I think that's been asked before. That'd be a massive undertaking, and they also support architectures that I don't think Rust does (yet).

You can already use experimental hyper backend (written in rust) for http stuff in curl https://aws.amazon.com/blogs/opensource/how-using-hyper-in-curl-can-help-make-the-internet-safer/ I wonder if the vulnerability touches this use case as well
