CVE-2026-42496 not yet assigned priority: Debian including 1 source packages (perl), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): open 5.
Archive::Tar versions before 3.08 for Perl extract symlinks with attacker controlled targets outside the extraction directory. _make_special_file() passes the tar header's linkname to symlink() without validating it against absolute paths or .. segments. The secure-extract mode check that guards regular file extraction does not cover the symlink target. A subsequent open through the extracted name reads or writes the attacker chosen path.
