CVE-2026-24857
Good to know:
Date: January 28, 2026
"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.
