Description
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.
Affected configurations
• envoyproxy envoy (< 1.27.6)
• envoyproxy envoy (>= 1.28.0 < 1.28.4)
• envoyproxy envoy (>= 1.29.0 < 1.29.5)
