The vulnerability is due to an incorrect allocation of an internal interface index. An adjacent attacker with the ability to submit a crafted FCoE packet that crosses affected interfaces could trigger this vulnerability. A successful exploit could allow the attacker to cause a packet loop and high throughput on the affected interfaces, resulting in a DoS condition. This vulnerability has been fixed in version 7.3(5)N1(1)."}, {"lang": "es", "value": "Una vulnerabilidad en la implementaci\u00f3n del protocolo Fibre Channel over Ethernet (FCoE) en el software NX-OS de Cisco podr\u00eda permitir a un atacante adyacente sin autenticar provocar una condici\u00f3n de denegaci\u00f3n de servicio (DoS) en un dispositivo afectado.
