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.
