Descriptions
A vulnerability in the network stack of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on the affected device. The vulnerability is due to an issue with allocating and freeing memory buffers in the network stack. An attacker could exploit this vulnerability by sending crafted TCP streams to an affected device in a sustained way. A successful exploit could cause the network stack of an affected device to run out of available buffers, impairing operations of control plane and management plane protocols, resulting in a DoS condition. Note: This vulnerability can be triggered only by traffic that is destined to an affected device and cannot be exploited using traffic that transits an affected device. Nexus 1000V Switch for Microsoft Hyper-V is affected in versions prior to 5.2(1)SM3(2.1). Nexus 1000V Switch for VMware vSphere is affected in versions prior to 5.2(1)SV3(4.1a). Nexus 3000 Series Switches are affected in versions prior to 7.0(3)I7(6) and 9.2(2). Nexus 3500 Platform Switches are affected in versions prior to 6.0(2)A8(11), 7.0(3)I7(6), and 9.2(2). Nexus 3600 Platform Switches are affected in versions prior to 7.0(3)F3(5) and 9.2(2). Nexus 5500, 5600, and 6000 Series Switches are affected in versions prior to 7.1(5)N1(1b) and 7.3(5)N1(1). Nexus 7000 and 7700 Series Switches are affected in versions prior to 6.2(22. Nexus 9500 R-Series Line Cards and Fabric Modules are affected in versions prior to 7.0(3)F3(5) and 9.2(2). UCS 6200 and 6300 Series Fabric Interconnect are affected in versions prior to 3.2(3j) and 4.0(2a). UCS 6400 Series Fabric Interconnect are affected in versions prior to 4.0(2a).
Una vulnerabilidad en la pila de red del software NX-OS de Cisco podría permitir a un atacante remoto sin autenticar provocar una condición de denegación de servicio (DoS) en un dispositivo afectado. Esta vulnerabilidad se debe a un fallo a la hora de asignar y librar búferes de memoria en la pila de red. Un atacante podría explotar esta vulnerabilidad enviando flujos TCP manipulados a un dispositivo afectado. Su explotación con éxito podría provocar que la red de pila de un dispositivo afectado agote los búferes disponibles, afectando a las operaciones de los protocolos control plane y management, conduciendo a una condición de denegación de servicio (DoS). Nota: esta vulnerabilidad puede desencadenarse solo por tráfico destinado a un dispositivo afectado y no puede explotarse mediante el uso de tráfico que transite por un dispositivo afectado. El switch de Nexus 1000V para Microsoft Hyper-V se ve afectado en versiones anteriores a la 5.2(1)SM3(2.1). El switch de Nexus 1000V para VMware vSphere se ve afectado en versiones anteriores a la 5.2(1)SV3(4.1a). Los switches de Nexus 3000 Series se ven afectados en versiones anteriores a las 7.0(3)I7(6) y 9.2(2). Los switches de Nexus 3500 Platform, se ven afectados en versiones anteriores a las 6.0(2)A8(11), 7.0(3)I7(6) y 9.2(2). Los switches de Nexus 3600 Platform se ven afectados en versiones anteriores a la 7.0(3)F3(5) y 9.2(2). Los switches de Nexus, en sus series 5500, 5600 y 6000, se ven afectados en versiones anteriores a las 7.1(5)N1(1b) y 7.3(5)N1(1). Los switches de Nexus, en sus series 7000 y 7700, se ven afectados en versiones anteriores a la 6.2(22). Los switches de 9500 R-Series Line Cards y Fabric Modules se ven afectados en versiones anteriores a las 7.0(3)F3(5) y 9.2(2). UCS 6200 y 6300 Series Fabric Interconnect, se ven afectados en versiones anteriores a las 3.2(3j) y 4.0(2a). UCS 6400 Series Fabric Interconnect, se ve afectado en versiones anteriores a la 4.0(2a).
