Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

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).
