Description OSIDB Bzimport 2026-05-28 15:01:57 UTC 
bzip2 contains an off‑by‑one error in the bzip2recover utility. When processing a specially crafted file, the application performs an out‑of‑bounds write to a global buffer, resulting in memory corruption and a crash (denial of service).

This issue was fixed in bzip2 version 1.0.9
