漏洞描述
中文描述:

Cisco NX-OS Software是美国思科（Cisco）公司的一套交换机使用的数据中心级操作系统软件。 Cisco FXOS Software和Cisco NX-OS Software中的Simple Network Management Protocol输入数据包处理器存在输入验证错误漏洞。该漏洞源于网络系统或产品未对输入的数据进行正确的验证。以下产品及版本受到影响：Cisco Firepower 4100 Series；Firepower 9300 Security Appliances；MDS 9000 Series Multilayer Switches；Nexus 1000V Switch for Microsoft Hyper-V；Nexus 1000V Switch for VMware vSphere；Nexus 3000 Series Switches；Nexus 3500 Platform Switches；Nexus 5500 Platform Switches；Nexus 5600 Platform Switches；Nexus 6000 Series Switches；Nexus 7000 Series Switches；Nexus 7700 Series Switches；Nexus 9000 Series Fabric Switches in Application Centric Infrastructure (ACI) mode；Nexus 9000 Series Switches in standalone NX-OS mode；Nexus 9500 R-Series Switching Platform。

英文描述:

A vulnerability in the Simple Network Management Protocol (SNMP) input packet processor of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause the SNMP application to leak system memory, which could cause an affected device to restart unexpectedly. The vulnerability is due to improper error handling when processing inbound SNMP packets. An attacker could exploit this vulnerability by sending multiple crafted SNMP packets to an affected device. A successful exploit could allow the attacker to cause the SNMP application to leak system memory because of an improperly handled error condition during packet processing. Over time, this memory leak could cause the SNMP application to restart multiple times, leading to a system-level restart and a denial of service (DoS) condition.
