Descriptions

The channel driver in Asterisk before 1.2.17 and 1.4.x before 1.4.2 allows remote attackers to cause a denial of service (crash) via a SIP INVITE message with an SDP containing one valid and one invalid IP address.

El controlador del canal en Asterisk en versiones anteriores a 1.2.17 y 1.4.x en versiones anteriores a 1.4.2 permite a atacantes remotos provocar una denegación de servicio (caída) a través de un mensaje SIP INVITE con un SDP que contiene una dirección IP válida y otra no válida.

The Madynes research team at INRIA has discovered that Asterisk contains a null pointer dereferencing error in the SIP channel when handling INVITE messages. Furthermore qwerty1979 discovered that Asterisk 1.2.x fails to properly handle SIP responses with return code 0. Versions less than 1.2.14-r2 are affected.
