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."}, {"lang": "es", "value": "Una vulnerabilidad en la clase LangChainLLM del repositorio run-llama/llama_index, versi\u00f3n v0.12.5, permite un ataque de denegaci\u00f3n de servicio (DoS).
