The jail(2) system call has not limited a visiblity of allocated TTYs (the kern.ttys sysctl). This gives rise to an information leak about processes outside the current jail.

Attacker can get information about TTYs allocated on the host or in other jails. Effectively, the information printed by “pstat -t” may be leaked.
