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 •

A memory exhaustion vulnerability exists in Asterisk Open Source 13.x before 13.15.1 and 14.x before 14.4.1 and Certified Asterisk 13.13 before 13.13-cert4, which can be triggered by sending specially crafted SCCP packets causing an infinite loop and leading to memory exhaustion (by message logging in that loop). Existe una vulnerabilidad de agotamiento de memoria en Asterisk Open Source, en versiones 13.x anteriores a la 13.15.1 y versiones 14.x anteriores a la 14.4.1, y en Certified Asterisk, en versiones 13.13 anteriores a la 13.13-cert4. Esto podría llevarse a cabo mediante el envío de paquetes SCCP especialmente manipulados que provocarían un bucle infinito y darían lugar a un agotamiento de memoria (mediante el registro de mensajes en ese bucle). • http://downloads.asterisk.org/pub/security/AST-2017-004.txt http://www.securityfocus.com/bid/98573 http://www.securitytracker.com/id/1038531 https://bugs.debian.org/863906 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

Remote code execution can occur in Asterisk Open Source 13.x before 13.14.1 and 14.x before 14.3.1 and Certified Asterisk 13.13 before 13.13-cert3 because of a buffer overflow in a CDR user field, related to X-ClientCode in chan_sip, the CDR dialplan function, and the AMI Monitor action. La ejecución remota de código puede ocurrir en Asterisk Open Source 13.x en versiones anteriores a 13.14.1 y 14.x en versiones anteriores a 14.3.1 y Asterisk certificado 13.13 en versiones anteriores a 13.13-cert3 debido a un desbordamiento de búfer en un campo de usuario de CDR, relacionado con X-ClientCode en chan_sip , La función de dialplan CDR y la acción Monitor AMI. • http://downloads.asterisk.org/pub/security/AST-2017-001.html http://www.securityfocus.com/bid/97377 https://bugs.debian.org/859910 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

https://notcve.org/view.php?id=CVE-2016-9938
An issue was discovered in Asterisk Open Source 11.x before 11.25.1, 13.x before 13.13.1, and 14.x before 14.2.1 and Certified Asterisk 11.x before 11.6-cert16 and 13.x before 13.8-cert4. The chan_sip channel driver has a liberal definition for whitespace when attempting to strip the content between a SIP header name and a colon character. Rather than following RFC 3261 and stripping only spaces and horizontal tabs, Asterisk treats any non-printable ASCII character as if it were whitespace. This means that headers such as Contact\x01: will be seen as a valid Contact header. This mostly does not pose a problem until Asterisk is placed in tandem with an authenticating SIP proxy. • http://downloads.asterisk.org/pub/security/AST-2016-009.html http://www.securityfocus.com/bid/94789 http://www.securitytracker.com/id/1037408 • CWE-285: Improper Authorization •
