CVE-2022-39294 – (DoS) Denial of Service from unchecked request length in conduit-hyper

https://notcve.org/view.php?id=CVE-2022-39294

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. • https://github.com/conduit-rust/conduit-hyper/security/advisories/GHSA-9398-5ghf-7pr6 • CWE-400: Uncontrolled Resource Consumption CWE-1284: Improper Validation of Specified Quantity in Input •
