      "value": "A vulnerability in the LangChainLLM class of the run-llama/llama_index repository, version v0.12.5, allows for a Denial of Service (DoS) attack. The stream_complete method executes the llm using a thread and retrieves the result via the get_response_gen method of the StreamingGeneratorCallbackHandler class. If the thread terminates abnormally before the _llm.predict is executed, there is no exception handling for this case, leading to an infinite loop in the get_response_gen function. This can be triggered by providing an input of an incorrect type, causing the thread to terminate and the process to continue running indefinitely."

El m\u00e9todo stream_complete ejecuta el llm mediante un hilo y recupera el resultado mediante el m\u00e9todo get_response_gen de la clase StreamingGeneratorCallbackHandler. Si el hilo termina de forma an\u00f3mala antes de ejecutar _llm.predict, no se gestionan excepciones, lo que genera un bucle infinito en la funci\u00f3n get_response_gen. Esto puede activarse al proporcionar una entrada de un tipo incorrecto, lo que provoca la finalizaci\u00f3n del hilo y la ejecuci\u00f3n indefinida del proceso."
