      "value": "A vulnerability in the Switch Integrated Security Features of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an interface queue wedge. The vulnerability is due to incorrect handling of crafted IPv6 packets. An attacker could exploit this vulnerability by sending crafted IPv6 packets through the device. An exploit could allow the attacker to cause an interface queue wedge. This vulnerability affects the Cisco cBR-8 Converged Broadband Router, Cisco ASR 1000 Series Aggregation Services Routers, and Cisco Cloud Services Router 1000V Series when configured with IPv6. In the field and internal testing, this vulnerability was only observed or reproduced on the Cisco cBR-8 Converged Broadband Router. The Cisco ASR 1000 Series Aggregation Services Routers and Cisco Cloud Services Router 1000V Series contain the same code logic, so affected trains have had the code fix applied; however, on these two products, the vulnerability has not been observed in the field or successfully reproduced internally. Cisco Bug IDs: CSCvd75185."

      "value": "Una vulnerabilidad en las características de seguridad integradas del switch en Cisco IOS XE Software podría permitir que un atacante remoto no autenticado haga que una cola de la interfaz se acuñe. Esta vulnerabilidad se debe a una gestión incorrecta de paquetes IPv6. Un atacante podría explotar esta vulnerabilidad enviando paquetes IPv6 manipulados a través del dispositivo. Su explotación podría permitir que el atacante haga que una cola de la interfaz se acuñe. Esta vulnerabilidad afecta al router Cisco cBR-8 Converged Broadband, los routers Cisco ASR 1000 Series Aggregation Services y al router Cisco Cloud Services 1000V Series. En producción y en las pruebas internas, la vulnerabilidad solo se observó o se reprodujo en el router Cisco cBR-8 Converged Broadband. Los routers Cisco ASR 1000 Series Aggregation Services y Cisco Cloud Services 1000V Series contienen la misma lógica de código, por lo que a los Trains afectados ya se les ha aplicado la solución de código; sin embargo, en estos dos productos la vulnerabilidad no ha sido observada en producción o reproducido internamente con éxito.
