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?
  
  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
  
  The lead developer's view: https://daniel.haxx.se/blog/2021/05/20/i-could-rewrite-curl/
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..."
