20 Sep 2018 — 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... • http://downloads.asterisk.org/pub/security/AST-2018-009.html • CWE-400: Uncontrolled Resource Consumption •

12 Jun 2018 — 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 ... • http://downloads.asterisk.org/pub/security/AST-2018-008.html • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

When processing a SUBSCRIBE request, the res_pjsip_pubsub module stores the accepted formats present in the Accept headers of the request. This code did not limit the number of headers it processed, despite having a fixed limit of 32. If more than 32 Accept headers were present, the code would write outside of its memory and cause a crash.

21 Feb 2018 — A NULL pointer access issue was discovered in Asterisk 15.x through 15.2.1. The RTP support in Asterisk maintains its own registry of dynamic codecs and desired payload numbers. While an SDP negotiation may result in a codec using a different payload number, these desired ones are still stored internally. When an RTP packet was received, this registry would be consulted if the payload number was not found in the negotiated SDP. This registry was incorrectly consulted for all packets, even those which are dy... • http://downloads.asterisk.org/pub/security/AST-2018-001.html • CWE-476: NULL Pointer Dereference •
