CVE-2026-24857

CRITICAL

9.8

Description

`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.
