An attacker could exploit this vulnerability by sending crafted UDP packets to an affected system. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition.\r\n\r Note: Only traffic that is directed to the affected system can be used to exploit this vulnerability. This vulnerability can be triggered by IPv4 and IPv6 traffic."}, {"lang": "es", "value": "Una vulnerabilidad en el c\u00f3digo de fragmentaci\u00f3n IKEv1 del software Cisco IOS y del software Cisco IOS XE podr\u00eda permitir que un atacante remoto no autenticado provoque un desbordamiento de almacenamiento din\u00e1mico, lo que provocar\u00eda la recarga del dispositivo afectado. Esta vulnerabilidad existe porque los paquetes IKEv1 fragmentados y elaborados no se vuelven a ensamblar correctamente. Un atacante podr\u00eda aprovechar esta vulnerabilidad enviando paquetes UDP manipulados a un sistema afectado.
