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 •
CVSS: 7.5EPSS: 78%CPEs: 7EXPL: 1CVE-2018-7284 – Asterisk chan_pjsip 15.2.0 - 'SUBSCRIBE' Stack Corruption
https://notcve.org/view.php?id=CVE-2018-7284
A Buffer Overflow issue was discovered in Asterisk through 13.19.1, 14.x through 14.7.5, and 15.x through 15.2.1, and Certified Asterisk through 13.18-cert2. 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. Se ha descubierto un problema de desbordamiento de búfer en Asterisk hasta la versión 13.19.1; versiones 14.x anteriores a la 14.7.5 y las versiones 15.x anteriores a la 15.2.1, así como Certified Asterisk hasta la versión 13.18-cert2. • https://www.exploit-db.com/exploits/44184 http://downloads.asterisk.org/pub/security/AST-2018-004.html http://www.securityfocus.com/bid/103151 http://www.securitytracker.com/id/1040416 https://www.debian.org/security/2018/dsa-4320 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

https://notcve.org/view.php?id=CVE-2017-17850
An issue was discovered in Asterisk 13.18.4 and older, 14.7.4 and older, 15.1.4 and older, and 13.18-cert1 and older. A select set of SIP messages create a dialog in Asterisk. Those SIP messages must contain a contact header. For those messages, if the header was not present and the PJSIP channel driver was used, Asterisk would crash. The severity of this vulnerability is somewhat mitigated if authentication is enabled. • http://downloads.asterisk.org/pub/security/AST-2017-014.html http://www.securitytracker.com/id/1040056 https://issues.asterisk.org/jira/browse/ASTERISK-27480 https://security.gentoo.org/glsa/201811-11 • CWE-20: Improper Input Validation •
