Envoy is vulnerable to a Use-After-Free vulnerability. The vulnerability is due to improper handling in HttpConnectionManager (HCM) with EnvoyQuicServerStream, where an attacker can crash Envoy by sending a request without FIN, followed by a RESET_STREAM frame, and then closing the connection after receiving the response.
