NVD Description

Note: Versions mentioned in the description apply only to the upstream perl-meta-notation package and not the perl-meta-notation package as distributed by Rocky-Linux. See How to fix? for Rocky-Linux:8 relevant fixed versions and status.

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.
