An Integer Signedness issue (for a return code) in the res_pjsip_sdp_rtp module in Digium Asterisk versions 15.7.1 and earlier and 16.1.1 and earlier allows remote authenticated users to crash Asterisk via a specially crafted SDP protocol violation. Un error en la propiedad signedness de un número entero (para código devuelto) en el módulo res_pjsip_sdp_rtp en Digium Asterisk, en versiones 15.7.1 y anteriores y en las 16.1.1 y anteriores, permite a los atacantes remotos no autenticados cerrar inesperadamente Asterisk mediante una violación de protocolo SDP especialmente manipulada. • https://downloads.asterisk.org/pub/security/AST-2019-001.html https://issues.asterisk.org/jira/browse/ASTERISK-28260 • CWE-190: Integer Overflow or Wraparound •

Buffer overflow in DNS SRV and NAPTR lookups in Digium Asterisk 15.x before 15.6.2 and 16.x before 16.0.1 allows remote attackers to crash Asterisk via a specially crafted DNS SRV or NAPTR response, because a buffer size is supposed to match an expanded length but actually matches a compressed length. Desbordamiento de búfer en las búsquedas DNS SRV y NAPTR en Digium Asterisk en versiones 15.x anteriores a la 15.6.2 y versiones 16.x anteriores a la 16.0.1 permite que atacantes remotos provoquen el cierre inesperado de Asterisk mediante una respuesta DNS SRV o NAPTR especialmente manipulada. Esto se debe a que se supone que un tamaño de búfer coincide con una longitud expandida, pero en realidad coincide con una longitud comprimida. • https://downloads.asterisk.org/pub/security/AST-2018-010.html https://issues.asterisk.org/jira/browse/ASTERISK-28127 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

There is a stack consumption vulnerability in the res_http_websocket.so module of Asterisk through 13.23.0, 14.7.x through 14.7.7, and 15.x through 15.6.0 and Certified Asterisk through 13.21-cert2. It allows an attacker to crash Asterisk via a specially crafted HTTP request to upgrade the connection to a websocket. Hay una vulnerabilidad de consumo de pila en el módulo res_http_websocket.so de Asterisk hasta la versión 13.23.0; versiones 14.7.x anteriores a la 14.7.7 y las versiones 15.x anteriores a la 15.6.0, así como Certified Asterisk hasta la versión 13.21-cert2. Permite que un atacante provoque el cierre inesperado de Asterisk mediante una petición HTTP para actualizar la conexión a un websocket. • http://downloads.asterisk.org/pub/security/AST-2018-009.html http://packetstormsecurity.com/files/149453/Asterisk-Project-Security-Advisory-AST-2018-009.html http://seclists.org/fulldisclosure/2018/Sep/31 http://www.securityfocus.com/bid/105389 http://www.securitytracker.com/id/1041694 https://issues.asterisk.org/jira/browse/ASTERISK-28013 https://lists.debian.org/debian-lts-announce/2018/09/msg00034.html https://seclists.org/bugtraq/2018/Sep/53 https://security.gentoo.org/glsa/201811&# • CWE-400: Uncontrolled Resource Consumption •

An issue was discovered in Asterisk Open Source 13.x before 13.21.1, 14.x before 14.7.7, and 15.x before 15.4.1 and Certified Asterisk 13.18-cert before 13.18-cert4 and 13.21-cert before 13.21-cert2. When endpoint specific ACL rules block a SIP request, they respond with a 403 forbidden. However, if an endpoint is not identified, then a 401 unauthorized response is sent. This vulnerability just discloses which requests hit a defined endpoint. The ACL rules cannot be bypassed to gain access to the disclosed endpoints. • http://downloads.asterisk.org/pub/security/AST-2018-008.html http://www.securityfocus.com/bid/104455 https://issues.asterisk.org/jira/browse/ASTERISK-27818 https://security.gentoo.org/glsa/201811-11 https://www.debian.org/security/2018/dsa-4320 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
