The vulnerability is due to an incorrect processing of FCoE packets when the fcoe-npv feature is uninstalled. An attacker could exploit this vulnerability by sending a stream of FCoE frames from an adjacent host to an affected device. An exploit could allow the attacker to cause packet amplification to occur, resulting in the saturation of interfaces and a DoS condition. Nexus 9000 Series Switches in Standalone NX-OS Mode are affected running software versions prior to 7.0(3)I7(5) and 9.2(2)."}, {"lang": "es", "value": "Una vulnerabilidad en la implementaci\u00f3n del protocolo Fibre Channel over Ethernet (FCoE) N-port Virtualization (NPV) 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). La vulnerabilidad se debe a un procesamiento incorrecto de paquetes FCoE cuando la funcionalidad fcoe-npv no est\u00e1 instalada.
