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, versión v0.12.5, permite un ataque de denegación de servicio (DoS). El método stream_complete ejecuta el llm mediante un hilo y recupera el resultado mediante el método get_response_gen de la clase StreamingGeneratorCallbackHandler. Si el hilo termina de forma anómala antes de ejecutar _llm.predict, no se gestionan excepciones, lo que genera un bucle infinito en la función get_response_gen. Esto puede activarse al proporcionar una entrada de un tipo incorrecto, lo que provoca la finalización del hilo y la ejecución indefinida del proceso."}],"metrics":{"cvssMetricV30":[{"source":"security@huntr.dev","type":"Secondary","cvssData":{"version":"3.0","vectorString":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":3.6}]},"weaknesses":[{"source":"security@huntr.dev","type":"Secondary","description":[{"lang":"en","value":"CWE-835"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:llamaindex:llamaindex:0.12.5:*:*:*:*:*:*:*","matchCriteriaId":"D35A0A81-3555-4025-9D5B-FE7435EA5747"}]}]}],"references":[{"url":"https://github.com/run-llama/llama_index/commit/d1ecfb77578d089cbe66728f18f635c09aa32a05","source":"security@huntr.dev","tags":["Patch"]},{"url":"https://huntr.com/bounties/a0b638fd-21c6-4ba7-b381-6ab98472a02a","source":"security@huntr.dev","tags":["Exploit","Third Party Advisory"]}]}}]}
