CVE-2024-32974

Summary

Envoy is a cloud-native, open source edge and service proxy. A crash was observed in EnvoyQuicServerStream::OnInitialHeadersComplete() with following call stack. It is a use-after-free caused by QUICHE continuing push request headers after StopReading() being called on the stream. As after StopReading(), the HCM's ActiveStream might have already be destroyed and any up calls from QUICHE could potentially cause use after free.
