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 •
