FTA: Stations that use vulnerable gear should upgrade to version 2.0-2, which is available by sending an e-mail to suport@digitalalertsystems.com.

As a "broadcast-emitting-messages-company" admin: would I really upgrade a system, which functionalities include complete take-over of my broadcast equipment, that is vulnerable to someone mistaking the private and public ssh keys of his "taking-over-any-equipment" equipment ?

I'd rather un-subscribe from that "service" in the limit of legality until that point of failure is fixed.
