The SIP channel driver (channels/chan_sip.c) in Asterisk Open Source 1.8.17.x through 1.8.22.x, 1.8.23.x before 1.8.23.1, and 11.x before 11.5.1 and Certified Asterisk 1.8.15 before 1.8.15-cert3 and 11.2 before 11.2-cert2 allows remote attackers to cause a denial of service (NULL pointer dereference, segmentation fault, and daemon crash) via an ACK with SDP to a previously terminated channel. NOTE: some of these details are obtained from third party information. El controlador de canal SIP (channel/chan_sip.c) en Asterisk Open Source 1.8.17.x hasta 1.8.22.x, 1.8.23.x (anteriores a 1.8.23.1), y 11.x (anteriores a 11.5.1); y Certified Asterisk 1.8.15 (anteriores a 1.8.15-cert3) y 11.2 (anteriores a 11.2-cert2) permiten a un atacante remoto causar una denegación de servicio (referencia a puntero nulo, corrupción de memoria y caída del demonio) a través de un ACK con SDP a un canal previamente cerrado.
