Descriptions

The PJSIP channel driver in Asterisk Open Source 12.x before 12.1.1, when qualify_frequency "is enabled on an AOR and the remote SIP server challenges for authentication of the resulting OPTIONS request," allows remote attackers to cause a denial of service (crash) via a PJSIP endpoint that does not have an associated outgoing request.

El controlador de canal PJSIP en Asterisk Open Source 12.x anterior a 12.1.1, cuando qualify_frequency "está habilitado en un AOR y el servidor SIP remoto desafía para autenticación de la solicitud OPTIONS resultante," permite a atacantes remotos causar una denegación de servicio (caída) a través de un Endpoint de PJSIP que no tiene una solicitud saliente asociada.

A remotely exploitable crash vulnerability exists in the PJSIP channel driver if the "qualify_frequency" configuration option is enabled on an AOR and the remote SIP server challenges for authentication of the resulting OPTIONS request. The response handling code wrongly assumes that a PJSIP endpoint will always be associated with an outgoing request which is incorrect.
