Todd Miller reports:

A (potentially malicious) program run by a user with sudo access may be able to bypass the "tty_ticket" constraints. In order for this to succeed there must exist on the machine a terminal device that the user has previously authenticated themselves on via sudo within the last time stamp timeout (5 minutes by default).
