CVE-2024-12704

Advisory

A vulnerability in the LangChainLLM class of the run-llama/llamaindex repository, version v0.12.5, allows for a Denial of Service (DoS) attack. The streamcomplete method executes the llm using a thread and retrieves the result via the getresponsegen 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 getresponse_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.
