The remote VoIP service can be abused to conduct an amplification
attack against third-party hosts.
The firmware download protocol implemented in the version of Asterisk
installed on the remote host does not initiate a handshake. By spoofing
an IAX2 FWDOWNL request, an unauthenticated, remote attacker may be able
to leverage this issue to flood a third-party host with unwanted
firmware packets from the affected host.
