Doc Text:
A flaw was found in Envoy. This flaw allows an attacker who controls an upstream host and also controls service discovery of that host (via DNS, the EDS API, etc.) to crash Envoy by forcing the removal of the host from service discovery and then failing the gRPC health check request. This issue crashes Envoy via a NULL pointer dereference.
