_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.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
