Envoy is a cloud-native, open source edge and service proxy. There is a use-after-free in HttpConnectionManager (HCM) with EnvoyQuicServerStream that can crash Envoy. An attacker can exploit this vulnerability by sending a request without FIN, then a RESET_STREAM frame, and then after receiving the response, closing the connection.
