CVE-2017-3857
https://notcve.org/view.php?id=CVE-2017-3857
A vulnerability in the Layer 2 Tunneling Protocol (L2TP) parsing function of Cisco IOS (12.0 through 12.4 and 15.0 through 15.6) and Cisco IOS XE (3.1 through 3.18) could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability is due to insufficient validation of L2TP packets. An attacker could exploit this vulnerability by sending a crafted L2TP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition. This vulnerability affects Cisco devices that are running a vulnerable release of Cisco IOS or Cisco IOS XE Software if the L2TP feature is enabled for the device and the device is configured as an L2TP Version 2 (L2TPv2) or L2TP Version 3 (L2TPv3) endpoint. • http://www.securityfocus.com/bid/97010 http://www.securitytracker.com/id/1038100 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170322-l2tp • CWE-399: Resource Management Errors CWE-400: Uncontrolled Resource Consumption •
CVE-2017-3864
https://notcve.org/view.php?id=CVE-2017-3864
A vulnerability in the DHCP client implementation of Cisco IOS (12.2, 12.4, and 15.0 through 15.6) and Cisco IOS XE (3.3 through 3.7) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability occurs during the parsing of a crafted DHCP packet. An attacker could exploit this vulnerability by sending crafted DHCP packets to an affected device that is configured as a DHCP client. A successful exploit could allow the attacker to cause a reload of an affected device, resulting in a DoS condition. This vulnerability affects Cisco devices that are running a vulnerable release of Cisco IOS or IOS XE Software and using a specific DHCP client configuration. • http://www.securityfocus.com/bid/97012 http://www.securitytracker.com/id/1038103 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170322-dhcpc • CWE-399: Resource Management Errors •
CVE-2016-6422
https://notcve.org/view.php?id=CVE-2016-6422
Cisco IOS 12.2(33)SXJ9 on Supervisor Engine 32 and 720 modules for 6500 and 7600 devices mishandles certain operators, flags, and keywords in TCAM share ACLs, which allows remote attackers to bypass intended access restrictions by sending packets that should have been recognized by a filter, aka Bug ID CSCuy64806. Cisco IOS 12.2(33)SXJ9 en los módulos Supervisor Engine 32 y 720 para dispositivos 6500 y 7600 no maneja adecuadamente ciertos operadores, indicadores y palabras clave en ACLs compartida con TCAM, lo que permite a atacantes remotos eludir las restricciones destinadas al acceso por el envío de paquetes que deberían haber sido reconocidos por un filtro, vulnerabilidad también conocida como Bug ID CSCuy64806. • http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20161005-catalyst http://www.securityfocus.com/bid/93404 http://www.securitytracker.com/id/1036954 • CWE-20: Improper Input Validation •

Cisco IOS 12.2 y 15.0 hasta la versión 15.3 permite a atacantes remotos provocar una denegación de servicio (interrupción del procesamiento de tráfico) a través de una serie de peticiones Common Industrial Protocol (CIP) manipuladas, vulnerabilidad también conocida como ID CSCur69036. • http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20160928-cip http://www.securityfocus.com/bid/93197 http://www.securitytracker.com/id/1036914 • CWE-399: Resource Management Errors •
CVE-2016-6380
https://notcve.org/view.php?id=CVE-2016-6380
The DNS forwarder in Cisco IOS 12.0 through 12.4 and 15.0 through 15.6 and IOS XE 3.1 through 3.15 allows remote attackers to obtain sensitive information from process memory or cause a denial of service (data corruption or device reload) via a crafted DNS response, aka Bug ID CSCup90532. El redireccionador de DNS en Cisco IOS 12.0 hasta la versión 12.4 y 15.0 hasta la versión 15.6 e IOS XE 3.1 hasta la versión 3.15 permite a atacantes remotos obtener información sensible de la memoria del proceso o provocar una denegación de servicio (corrupción de datos o reinicio del dispositivo) a través de una respuesta DNS manipulada, vulnerabilidad también conocida como Bug ID CSCup90532. • http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20160928-dns http://www.securityfocus.com/bid/93201 http://www.securitytracker.com/id/1036914 https://ics-cert.us-cert.gov/advisories/ICSA-16-287-04 • CWE-20: Improper Input Validation •
