Kerentanan Improper Link Resolution Before File Access ('Link Following') pada archive . Skor CVSS 3.1 9.1 (Critical) menurut NVD.

Deskripsi (NVD)

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.
