Prior to version 0.4.2, `conduit-hyper` did not check any limit on a request's length before calling `hyper::body::to_bytes`. 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").
