Recommendation: Monitor — no exploitation signal at the moment.
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.
