CVE-2018-15373 (CNNVD-201809-1268)
中文标题:
Cisco IOS Software和IOS XE Software 资源管理错误漏洞
英文标题:
Cisco IOS and IOS XE Software Cisco Discovery Protocol Denial of Service Vulnerability
漏洞描述
中文描述:
Cisco IOS Software和IOS XE Software都是美国思科（Cisco）公司为其网络设备开发的操作系统。 Cisco IOS Software和IOS XE Software中Cisco Discovery Protocol功能的实现存在资源管理错误漏洞，该漏洞源于在处理高频率的Cisco Discovery Protocol数据包时受影响的软件没有正确的处理内存。攻击者可通过发送高频的数据包利用该漏洞造成拒绝服务（内存耗尽）。
英文描述:
A vulnerability in the implementation of Cisco Discovery Protocol functionality in Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to exhaust memory on an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to improper memory handling by the affected software when the software processes high rates of Cisco Discovery Protocol packets that are sent to a device. An attacker could exploit this vulnerability by sending a high rate of Cisco Discovery Protocol packets to an affected device. A successful exploit could allow the attacker to exhaust memory on the affected device, resulting in a DoS condition.
