Audit `http` #37

Open thomcc opened 5 years ago

thomcc commented 5 years ago

This is a very popular crate (10k downloads / day, >2M all time), and is also a potential attack target, due to the fact that it is intended to be exposed directly to the network.

It does some tricky stuff with unsafe that's I've always felt was worth a close look at. In particular the HeaderMap and related code is quite complex and uses a lot of unsafe. The rest of the crate uses less, but still some.

I started looking into the code, and I'm about halfway done; I will open issues about my finding and keep this thread updated.

Reported hyperium/http#352, hyperium/http#353, hyperium/http#354, and hyperium/http#355. I don't have enough time to work on PRs in the mean time, so I would appreciate it if someone else can take care of theese issues.
