"There are few prerequisites for the attack to work: the user much be
listed in the /etc/sudoers file; must have successfully authenticated
to execute a sudo command once; and it must be possible for users to
modify the system time without entering a password."

Having someone upgrade his/her sudo privileges to "NOPASSWD:" isn't
good but it isn't the end of the world when compared to an external
attacker getting access to a system.
