Asterisk Open Source 12.x before 12.8.1 and 13.x before 13.1.1, when using the PJSIP channel driver, does not properly reclaim RTP ports, which allows remote authenticated users to cause a denial of service (file descriptor consumption) via an SDP offer containing only incompatible codecs. Asterisk Open Source 12.x anterior a 12.8.1 y 13.x anterior a 13.1.1, cuando utiliza el controlador de canales PJSIP, no recupera correctamente los puertos RTP, lo que permite a usuarios remotos autenticados causar una denegación de servicio (consumo del descriptor de ficheros) a través de una oferta SDP que contiene solamente codecs incompatibles. • http://downloads.asterisk.org/pub/security/AST-2015-001.html http://seclists.org/fulldisclosure/2015/Jan/116 http://www.securityfocus.com/archive/1/534573/100/0/threaded http://www.securitytracker.com/id/1031661 • CWE-399: Resource Management Errors •
