Descriptions

The SIP channel driver (chan_sip) in Asterisk before 1.2.18 and 1.4.x before 1.4.3 does not properly parse SIP UDP packets that do not contain a valid response code, which allows remote attackers to cause a denial of service (crash).

El SIP channel driver (chan_sip) del Asterisk anterior al 1.2.18 y el 1.4.x anterior al 1.4.3 no analiza sintácticamente de forma correcta los paquetes SIP UDP que no contienen un código de respuesta válido, lo que permite a atacantes remotos provocar una denegación de servicio (caída).

Several remote vulnerabilities have been discovered in Asterisk, a free software PBX and telephony toolkit. These flaws range from denial of service to code execution vulnerabilities.
