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?

[–] ultratiem@lemmy.ca 12 points 1 year ago (1 children)

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@programming.dev 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

Perfect article for my question. Appreciated.

I want to thank the curl developers for taking security issues seriously to keep me safe.

Now I'm going to go pipe another curl script output directly into a sudo bash command. /s

We need a version of /s for "I'm not actually doing this right now... but we know I still will..."
