conduit-hyper integrates a conduit application with the hyper server. Prior to version 0.4.2, `conduit-hyper` did not check any limit on a request's length before calling [`hyper::body::to_bytes`](https://docs.rs/hyper/latest/hyper/body/fn.to_bytes.html). An attacker could send a malicious request with an abnormally large `Content-Length`, which could lead to a panic if memory allocation failed for that request. In version 0.4.2, `conduit-hyper` sets an internal limit of 128 MiB per request, otherwise returning status 400 ("Bad Request"). This crate is part of the implementation of Rust's [crates.io](https://crates.io/), but that service is not affected due to its existing cloud infrastructure, which already drops such malicious requests. Even with the new limit in place, `conduit-hyper` is not recommended for production use, nor to directly serve the public Internet.
