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").
