      "value": "A Thrift client in Apache bRPC (version < 1.18.0, built with WITH_THRIFT which is off by default) can be crashed by the server peer it talks to. When the server returns a T_EXCEPTION reply whose exception struct is malformed, the client decodes it without catching what Apache Thrift throws (TProtocolException, TTransportException or std::length_error). The exception unwinds out of the bthread task function and the process calls std::terminate(), terminating the whole process along with every other in-flight RPC.\n\nThis is the client response path, so the adversary is the server peer, which THREAT_MODEL.md treats as untrusted. It requires a WITH_THRIFT build (off by default).\n\nHow to Fix:\n1. Upgrade bRPC to version 1.18.0, which fixes this issue.\n2. Apply this patch: https://github.com/apache/brpc/pull/3500"

      "value": "Un cliente Thrift en Apache bRPC (versiones anteriores a la 1.18.0, compilado con WITH_THRIFT, que está desactivado por defecto) puede ser bloqueado por el par servidor con el que se comunica. Cuando el servidor devuelve una respuesta T_EXCEPTION cuya estructura de excepción está malformada, el cliente la decodifica sin capturar lo que Apache Thrift lanza (TProtocolException, TTransportException o std::length_error). La excepción se propaga fuera de la función de tarea bthread y el proceso llama a std::terminate(), terminando todo el proceso junto con cualquier otra RPC en curso.\\n\\nEsta es la ruta de respuesta del cliente, por lo que el adversario es el par servidor, que THREAT_MODEL.md trata como no confiable. Requiere una compilación WITH_THRIFT (desactivada por defecto).\\n\\nCómo corregir:\\n1. Actualizar bRPC a la versión 1.18.0, que soluciona este problema.\\n2.
