The vulnerability is due to insufficient error handling when parsing DNS requests. An attacker could exploit this vulnerability by sending a series of malicious DNS requests to an Umbrella Connector client interface of an affected device. A successful exploit could allow the attacker to cause a crash of the iosd process, which triggers a reload of the affected device."},{"lang":"es","value":"Una vulnerabilidad en el componente Umbrella Connector de Cisco IOS XE Software para Cisco Catalyst 9200 Series Switches, podría permitir a un atacante remoto no autenticado desencadenar una recarga, resultando en una condición de denegación de servicio en un dispositivo afectado. La vulnerabilidad es debido a un manejo insuficiente de errores cuando se analizan las peticiones DNS. Un atacante podría explotar esta vulnerabilidad mediante el envío de una serie de peticiones DNS maliciosas a una interfaz del cliente de Umbrella Connector de un dispositivo afectado. Una explotación con éxito podría permitir al atacante causar un bloqueo del
