Umm. Maybe in *that step* it's "at most". But what can you leverage that into? If you can screw with the code execution of the tar command enough to get root to untar a file of your choosing, you then have your entire rootkit installed with no further effort on your part. ;) (For a wonderful read on leveraging, find the tech writeup from a few years ago on how a 1-byte overlay in ntpd got leveraged into a total root pwn.)
