漏洞描述
中文描述:

Cisco Nexus 9000 Series Fabric Switches是美国思科（Cisco）公司的一款9000系列交换机产品。 Cisco Nexus 9000 Series Fabric Switches（处于ACI模式）13.0(1k)版本中的DHCPv6功能存在拒绝服务漏洞，该漏洞源于程序在目标设备的接口上接收DHCPv6数据包时没有正确的管理内存。远程攻击者可通过发送大量的恶意的DHCPv6数据包利用该漏洞造成拒绝服务。

英文描述:

A vulnerability in the DHCPv6 feature of the Cisco Nexus 9000 Series Fabric Switches in Application-Centric Infrastructure (ACI) Mode could allow an unauthenticated, remote attacker to cause the device to run low on system memory, which could result in a Denial of Service (DoS) condition on an affected system. The vulnerability is due to improper memory management when DHCPv6 packets are received on an interface of the targeted device. An attacker could exploit this vulnerability by sending a high number of malicious DHCPv6 packets to be processed by an affected device. A successful exploit could allow the attacker to cause the system to run low on memory, which could cause an eventual reboot of an affected device. The vulnerability only applies to IPv6 protocol packets and not for IPv4 protocol packets. This vulnerability affects Cisco Nexus 9000 Series Fabric Switches in ACI Mode running software version 13.0(1k). The vulnerability can only be exploited when unicast routing is enabled on the Bridge Domain (BD). DHCP and DHCP relay do not have to be configured for the vulnerability to be exploited. Cisco Bug IDs: CSCvg38918.
