>Description:
      On the assumption that jail should create a virtual environment from which the prisoner sees nothing apart from their jail, then ifconfig discloses interfaces other than it's own.

>How-To-Repeat:
      Create a jail and run within that jail and ifconfig prints out all interfaces, not just the interface/address associated with the jail.
