CVE-2024-32974

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.

Summary		(es) Envoy es un proxy de servicio y borde de código abierto, nativo de la nube. Se observó un bloqueo en `EnvoyQuicServerStream::OnInitialHeadersComplete()` con la siguiente pila de llamadas. Es un use-after-free causado porque QUICHE continúa enviando encabezados de solicitud después de que se llama a `StopReading()` en la secuencia. Al igual que después de `StopReading()`, es posible que el `ActiveStream` del HCM ya se haya destruido y cualquier llamada desde QUICHE podría provocar su use after free.
