CVSS: 6.5EPSS: 20%CPEs: 5EXPL: 1CVE-2018-7286 – Asterisk chan_pjsip 15.2.0 - 'INVITE' Denial of Service
https://notcve.org/view.php?id=CVE-2018-7286
An 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. res_pjsip allows remote authenticated users to crash Asterisk (segmentation fault) by sending a number of SIP INVITE messages on a TCP or TLS connection and then suddenly closing the connection. Se ha descubierto un problema en Asterisk hasta la versión 13.19.1, versiones 14.x hasta la 14.7.5 y versiones 15.x hasta la 15.2.1; así como Certified Asterisk hasta la versión 13.18-cert2. res_pjsip permite que usuarios remotos autenticados provoquen el cierre inesperado de Asterisk (fallo de segmentación) mediante el envío de mensajes SIP INVITE en una conexión TCP o TLS para después cerrar la conexión repentinamente. Asterisk running chan_pjsip suffers from an INVITE message denial of service vulnerability. Versions affected include Versions affected include 15.2.0, 15.1.0, 15.0.0, 13.19.0, 13.11.2, and 14.7.5. • https://www.exploit-db.com/exploits/44181 http://downloads.asterisk.org/pub/security/AST-2018-005.html http://www.securityfocus.com/bid/103129 http://www.securitytracker.com/id/1040417 https://issues.asterisk.org/jira/browse/ASTERISK-27618 https://www.debian.org/security/2018/dsa-4320 •

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 •

PJSIP, as used in Asterisk Open Source 13.x before 13.15.1 and 14.x before 14.4.1, Certified Asterisk 13.13 before 13.13-cert4, and other products, allows remote attackers to cause a denial of service (buffer overflow and application crash) via a SIP packet with a crafted CSeq header in conjunction with a Via header that lacks a branch parameter. PJSIP, tal como es usado en Asterisk Open Source versiones 13.x y anteriores a 13.15.1 y versiones 14.x y anteriores a 14.4.1, Certified Asterisk versión 13.13 y anteriores a 13.13-cert4, y otros productos, permite a los atacantes remotos causar una denegación de servicio (desbordamiento de búfer y bloqueo de aplicación) por medio de un paquete SIP con un encabezado CSeq especialmente diseñado junto con un encabezado Via que carece de un parámetro branch. • http://downloads.asterisk.org/pub/security/AST-2017-002.txt http://www.debian.org/security/2017/dsa-3933 http://www.securityfocus.com/bid/98572 http://www.securitytracker.com/id/1038529 https://bugs.debian.org/863901 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
