Tar does set setuid bit, but tar is not vulnerable. This is not an attack.
The user is responsible for extracting the archives to secure location
and not letting other users access to insecure setuid binaries. See:
https://www.gnu.org/software/tar/manual/html_section/Security.html#Security-rules-of-thumb
These same security considerations also apply to cpio.
