An issue was discovered in res_http_websocket.c in Asterisk 15.x through 15.2.1. If the HTTP server is enabled (default is disabled), WebSocket payloads of size 0 are mishandled (with a busy loop). Se ha descubierto un problema en res_http_websocket.c en Asterisk hasta la versión 15.2.1. Si el servidor HTTP está habilitado (está deshabilitado por defecto), las cargas útiles de WebSocket de tamaño 0 se gestionan de forma incorrecta (con un bucle ocupado). • http://downloads.digium.com/pub/security/AST-2018-006.html http://www.securityfocus.com/bid/103120 http://www.securitytracker.com/id/1040419 https://issues.asterisk.org/jira/browse/ASTERISK-27658 • CWE-754: Improper Check for Unusual or Exceptional Conditions •

https://notcve.org/view.php?id=CVE-2018-7285
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 dynamic. • http://downloads.asterisk.org/pub/security/AST-2018-001.html http://www.securityfocus.com/bid/103149 http://www.securitytracker.com/id/1040415 • CWE-476: NULL Pointer Dereference •

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 •

A Remote Crash issue was discovered in Asterisk Open Source 13.x before 13.18.4, 14.x before 14.7.4, and 15.x before 15.1.4 and Certified Asterisk before 13.13-cert9. Certain compound RTCP packets cause a crash in the RTCP Stack. Se ha descubierto un problema de cierre inesperado remoto en Asterisk Open Source en versiones 13.x anteriores a la 13.18.4; versiones 14.x anteriores a la 14.7.4 y las versiones 15.x anteriores a la 15.1.4, así como Certified Asterisk en versiones anteriores a la 13.13-cert9. Ciertos paquetes compuestos RTCP pueden provocar un cierre inesperado en la pila RTCP. • http://downloads.digium.com/pub/security/AST-2017-012.html http://www.securityfocus.com/bid/102201 http://www.securitytracker.com/id/1040009 https://issues.asterisk.org/jira/browse/ASTERISK-27382 https://issues.asterisk.org/jira/browse/ASTERISK-27429 https://www.debian.org/security/2017/dsa-4076 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 7.5EPSS: 69%CPEs: 15EXPL: 1CVE-2017-17090 – Asterisk 13.17.2 - 'chan_skinny' Remote Memory Corruption
https://notcve.org/view.php?id=CVE-2017-17090
An issue was discovered in chan_skinny.c in Asterisk Open Source 13.18.2 and older, 14.7.2 and older, and 15.1.2 and older, and Certified Asterisk 13.13-cert7 and older. If the chan_skinny (aka SCCP protocol) channel driver is flooded with certain requests, it can cause the asterisk process to use excessive amounts of virtual memory, eventually causing asterisk to stop processing requests of any kind. Se ha descubierto un problema en chan_skinny.c en Asterisk Open Source en versiones 13.18.2 y anteriores, 14.7.2 y anteriores y 15.1.2 y anteriores y en Certified Asterisk 13.13-cert7 y anteriores. Si el controlador de canal chan_skinny (también conocido como protocolo SCCP) se inunda a base de determinadas peticiones, puede provocar que el proceso de asterisk utilice cantidades excesivas de memoria virtual, finalmente provocando que asterisk deje de procesar cualquier tipo de peticiones. • https://www.exploit-db.com/exploits/43992 http://downloads.digium.com/pub/security/AST-2017-013.html http://www.securityfocus.com/bid/102023 http://www.securitytracker.com/id/1039948 https://issues.asterisk.org/jira/browse/ASTERISK-27452 https://lists.debian.org/debian-lts-announce/2017/12/msg00028.html https://www.debian.org/security/2017/dsa-4076 • CWE-459: Incomplete Cleanup •
