+# Denial of Service from unchecked request length
+
+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").
