GHSA-g588-cjg3-6g78
Processing the raw `ValidateAuthTicketResponse_t` callback data panics when the `m_eAuthSessionResponse` field is `k_EAuthSessionResponseAuthTicketNetworkIdentityFailure`. This can lead to denial of service in game clients and servers using the `begin_authentication_session` API to authenticate players if a malicious game client sends an authentication ticket with a network identity that does not match that of the verifier.
