"value": "A vulnerability in the DHCPv6 relay agent of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.\r\n\r\nThis vulnerability is due to improper handling of specific fields in a DHCPv6 RELAY-REPLY message. An attacker could exploit this vulnerability by sending a crafted DHCPv6 packet to any IPv6 address that is configured on an affected device. A successful exploit could allow the attacker to cause the dhcp_snoop process to crash and restart multiple times, causing the affected device to reload and resulting in a DoS condition."

"value": "Una vulnerabilidad en el agente de retransmisi\u00f3n DHCPv6 de Cisco NX-OS Software podr\u00eda permitir que un atacante remoto no autenticado provoque una condici\u00f3n de denegaci\u00f3n de servicio (DoS) en un dispositivo afectado. Esta vulnerabilidad se debe a un manejo inadecuado de campos espec\u00edficos en un mensaje RELAY-REPLY de DHCPv6. Un atacante podr\u00eda aprovechar esta vulnerabilidad enviando un paquete DHCPv6 manipulado a cualquier direcci\u00f3n IPv6 que est\u00e9 configurada en un dispositivo afectado. Una explotaci\u00f3n exitosa podr\u00eda permitir que el atacante provoque que el proceso dhcp_snoop se bloquee y se reinicie varias veces, lo que hace que el dispositivo afectado se recargue y genere una condici\u00f3n de DoS."
