CVE-2007-1693

Estado: ModificadaAlta (7.8)—

El módulo de canal SIP en Yet Another Telephony (Yate) en versiones anteriores a 1.2.0 establece el parámetro caller_info_uri usando una variable incorrecta que puede ser NULO, lo que permite a atacantes remótos causar una denegación del servicio (referencia a puntero NULO y caída de aplicación) a través de una cabecera Call-Info sin un parámetro concreto.
