bulk_extractor has Heap-based Buffer Overflow vulnerability

bulk_extractor is a digital forensics exploitation tool. Starting in version 1.4, bulk_extractor’s embedded unrar code has a heap‑buffer‑overflow in the RAR PPM LZ decoding path. A crafted RAR inside a disk image causes an out‑of‑bounds write in Unpack::CopyString, leading to a crash under ASAN (and likely a crash or memory corruption in production builds). There's potential for using this for RCE. As of time of publication, no known patches are available.
