Critical Vulnerability in llama.cpp Server
Read Full Article: Critical Vulnerability in llama.cpp Server
llama.cpp, a C/C++ implementation for running large language models, has a critical vulnerability in its server's completion endpoints. The issue arises from the n_discard parameter, which is parsed from JSON input without validation to ensure it is non-negative. If a negative value is used, it can lead to out-of-bounds memory writes during token evaluation, potentially crashing the process or allowing remote code execution. This vulnerability is significant as it poses a security risk for users running llama.cpp, and there is currently no fix available. Understanding and addressing such vulnerabilities is crucial to maintaining secure systems and preventing exploitation.
