A vulnerability in auxiliary asynchronous port (AUX) functions of Cisco IOS XE Software could allow an authenticated, local attacker to cause an affected device to reload or stop responding. This vulnerability is due to the incorrect handling of specific ingress traffic when flow control hardware is enabled on the AUX port. An attacker could exploit this vulnerability by reverse telnetting to the AUX port and sending specific data after connecting. A successful exploit could allow the attacker to cause the device to reset or stop responding, resulting in a denial of service (DoS) condition. Una vulnerabilidad en las funciones del puerto asíncrono auxiliar (AUX) del software Cisco IOS XE podría permitir que un atacante local autenticado provoque que un dispositivo afectado se recargue o deje de responder. Esta vulnerabilidad se debe al manejo incorrecto del tráfico de entrada específico cuando el hardware de control de flujo está habilitado en el puerto AUX. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-aux-333WBz8f • CWE-828: Signal Handler with Functionality that is not Asynchronous-Safe •

A vulnerability in the Intermediate System-to-Intermediate System (IS-IS) protocol of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient input validation when parsing an ingress IS-IS packet. An attacker could exploit this vulnerability by sending a crafted IS-IS packet to an affected device after forming an adjacency. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition. Note: The IS-IS protocol is a routing protocol. To exploit this vulnerability, an attacker must be Layer 2-adjacent to the affected device and have formed an adjacency. Una vulnerabilidad en el protocolo de sistema intermedio a sistema intermedio (IS-IS) del software Cisco IOS y del software Cisco IOS XE podría permitir que un atacante adyacente no autenticado cause una condición de denegación de servicio (DoS) en un dispositivo afectado. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-isis-sGjyOUHX • CWE-476: NULL Pointer Dereference •

A vulnerability in the Locator ID Separation Protocol (LISP) feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. This vulnerability is due to the incorrect handling of LISP packets. An attacker could exploit this vulnerability by sending a crafted LISP packet to an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a denial of service (DoS) condition. Note: This vulnerability could be exploited over either IPv4 or IPv6 transport. Una vulnerabilidad en la función del Protocolo de separación de ID del localizador (LISP) del software Cisco IOS y del software Cisco IOS XE podría permitir que un atacante remoto no autenticado provoque la recarga de un dispositivo afectado. Esta vulnerabilidad se debe al manejo incorrecto de los paquetes LISP. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-lisp-3gYXs3qP • CWE-674: Uncontrolled Recursion •
