Descriptions

chan_sip.c in Asterisk Open Source 1.8.x before 1.8.8.2 and 10.x before 10.0.1, when the res_srtp module is used and media support is improperly configured, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted SDP message with a crypto attribute and a (1) video or (2) text media type, as demonstrated by CSipSimple.

chan_sip.c en Asterisk Open Source v1.8.x antes de v1.8.8.2 y v10.x antes de v10.0.1 , cuando se usa el módulo res_srtp y el soporte multimedia esta incorrectamente configurado, permite a atacantes remotos provocar una denegación de servicio (puntero a NULL y caída del demonio) a través de un mensaje SDP específicamente modificado con un atributo de cifrado y (1) un vídeo o (2) el tipo de medio 'text'. Esto queda demostrado con CSipSimple.

A vulnerability in Asterisk could allow a remote attacker to cause a Denial of Service condition. Versions less than 1.8.8.2 are affected.
