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 "early audio" 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. El IAX2 channel driver (chan_iax2) en Asterisk 1.2 anterior a la revisión 72630 y 1.4 anterior a la revisión 65679, cuando está configurado para permitir llamadas sin autenticación, envía "early audio" a una IP sin verificar de un mensaje NEW, lo que permite a atacantes remotos provocar una denegación de servicio (amplificación del tráfico) a través de un mensaje NEW falseado. • http://bugs.digium.com/view.php?id=10078 http://downloads.digium.com/pub/security/AST-2008-006.html http://www.altsci.com/concepts/page.php?s=asteri&p=1 https://exchange.xforce.ibmcloud.com/vulnerabilities/42049 • CWE-16: Configuration •

The IAX2 channel driver (chan_iax2) in Asterisk Open Source 1.0.x, 1.2.x before 1.2.28, and 1.4.x before 1.4.19.1; Business Edition A.x.x, B.x.x before B.2.5.2, and C.x.x before C.1.8.1; AsteriskNOW before 1.0.3; Appliance Developer Kit 0.x.x; and s800i before 1.1.0.3, when configured to allow unauthenticated calls, does not verify that an ACK response contains a call number matching the server's reply to a NEW message, which allows remote attackers to cause a denial of service (traffic amplification) via a spoofed ACK response that does not complete a 3-way handshake. NOTE: this issue exists because of an incomplete fix for CVE-2008-1923.
