The IAX2 channel driver (chan_iax2) in Asterisk 1.2 before revision 72630
and 1.4 before revision 65679, when configured to allow unauthenticated
calls, sends βearly audioβ to an unverified source IP address of a NEW
message, which allows remote attackers to cause a denial of service
(traffic amplification) via a spoofed NEW message.
