NVD Description
Note: Versions mentioned in the description apply only to the upstream llama.cpp package and not the llama.cpp package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
llama.cpp is an inference of several LLM models in C/C++. Prior to version b5721, there is a signed vs. unsigned integer overflow in llama.cpp's tokenizer implementation (llama_vocab::tokenize) (src/llama-vocab.cpp:3036) resulting in unintended behavior in tokens copying size comparison. Allowing heap-overflowing llama.cpp inferencing engine with carefully manipulated text input during tokenization process. This issue has been patched in version b5721.
