The vulnerability is due to improper handling of packets by the IPsec packet processor. An attacker could exploit this vulnerability by sending malicious ICMP error messages to an affected device that get punted to the IPsec packet processor. A successful exploit could allow the attacker to deplete IPsec memory, resulting in all future IPsec packets to an affected device being dropped by the device. Manual intervention is required to recover from this situation."}, {"lang": "es", "value": "Una vulnerabilidad en el procesador de paquetes IPsec de Cisco IOS XR Software, podr\u00eda permitir a un atacante remoto no autenticado causar una condici\u00f3n de denegaci\u00f3n de servicio (DoS) para sesiones IPsec en un dispositivo afectado. La vulnerabilidad es debido al manejo inapropiado de los paquetes por parte del procesador de paquetes IPsec.
