CVE-2024-34362: Envoy affected by a crash (use-after-free) in EnvoyQuicServerStream

First published: Tue Jun 04 2024(Updated: )

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.
