The vulnerability is due to incorrect processing of Border Gateway Protocol (BGP) update messages that contain crafted EVPN attributes. An attacker could exploit this vulnerability by sending BGP update messages with specific, malformed attributes to an affected device. A successful exploit could allow the attacker to cause an affected device to crash, resulting in a DoS condition."},{"lang":"es","value":"Una vulnerabilidad en la implementación de Multiprotocol Border Gateway Protocol (MP-BGP) para la familia de direcciones Layer 2 VPN (L2VPN) Ethernet VPN (EVPN) en Cisco IOS Software y Cisco IOS XE Software, podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS). La vulnerabilidad es debido al procesamiento incorrecto de los mensajes de actualización del Border Gateway Protocol (BGP) que contienen atributos EVPN diseñados. Un atacante podría explotar esta vulnerabilidad mediante el envío mensajes de actualización de BGP con atributos específicos malformado hacia un dispositivo
