漏洞描述
中文描述:
Cisco Link Layer Discovery Protocol是美国思科（Cisco）公司的一个路由器。 Link Layer Discovery Protocol 存在缓冲区错误漏洞，未经身份验证的相邻攻击者可利用该漏洞可以执行任意代码。
英文描述:
Multiple vulnerabilities exist in the Link Layer Discovery Protocol (LLDP) implementation for Cisco Small Business RV Series Routers. An unauthenticated, adjacent attacker could execute arbitrary code or cause an affected router to leak system memory or reload. A memory leak or device reload would cause a denial of service (DoS) condition on an affected device. For more information about these vulnerabilities, see the Details section of this advisory. Note: LLDP is a Layer 2 protocol. To exploit these vulnerabilities, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent).
