CVE-2011-4089 low priority: Debian including 1 source packages (bzip2), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
The bzexe command in bzip2 1.0.5 and earlier generates compressed executables that do not properly handle temporary files during extraction, which allows local users to execute arbitrary code by precreating a temporary directory.
