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 •

An issue was discovered in Asterisk Open Source 13 before 13.18.1, 14 before 14.7.1, and 15 before 15.1.1 and Certified Asterisk 13.13 before 13.13-cert7. A memory leak occurs when an Asterisk pjsip session object is created and that call gets rejected before the session itself is fully established. When this happens the session object never gets destroyed. Eventually Asterisk can run out of memory and crash. Se descubrió un problema en Asterisk Open Source en versiones 13 anteriores a la 13.18.1, versiones 14 anteriores a la 14.7.1 y versiones 15 antes de la 15.1.1 y en Certified Asterisk 13.13 en versiones anteriores a la 13.13-cert7. • http://downloads.digium.com/pub/security/AST-2017-011.html http://www.securityfocus.com/bid/101765 https://issues.asterisk.org/jira/browse/ASTERISK-27345 https://security.gentoo.org/glsa/201811-11 https://www.debian.org/security/2017/dsa-4076 • CWE-772: Missing Release of Resource after Effective Lifetime •

A Buffer Overflow issue was discovered in Asterisk Open Source 13 before 13.18.1, 14 before 14.7.1, and 15 before 15.1.1 and Certified Asterisk 13.13 before 13.13-cert7. No size checking is done when setting the user field for Party B on a CDR. Thus, it is possible for someone to use an arbitrarily large string and write past the end of the user field storage buffer. NOTE: this is different from CVE-2017-7617, which was only about the Party A buffer. Una vulnerabilidad de desbordamiento de búfer se descubrió en Asterisk Open Source en versiones 13 anteriores a la 13.18.1, versiones 14 anteriores a la 14.7.1 y versiones 15 antes de la 15.1.1 y en Certified Asterisk 13.13 en versiones anteriores a la 13.13-cert7. • http://downloads.digium.com/pub/security/AST-2017-010.html http://www.securityfocus.com/bid/101760 https://issues.asterisk.org/jira/browse/ASTERISK-27337 https://security.gentoo.org/glsa/201811-11 https://www.debian.org/security/2017/dsa-4076 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
