Cisco Video Surveillance 7000 Series IP Cameras Link Layer Discovery Protocol Memory Leak Vulnerabilities

Multiple vulnerabilities in the Link Layer Discovery Protocol (LLDP) implementation for Cisco Video Surveillance 7000 Series IP Cameras could allow an unauthenticated, adjacent attacker to cause a memory leak, which could lead to a denial of service (DoS) condition on an affected device. These vulnerabilities are due to incorrect processing of certain LLDP packets at ingress time. An attacker could exploit these vulnerabilities by sending crafted LLDP packets to an affected device. A successful exploit could allow the attacker to cause the affected device to continuously consume memory, which could cause the device to crash and reload, resulting in a DoS condition. 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).

Cisco Video Surveillance 7000 安全漏洞

Cisco Video Surveillance 7000 Series IP Cameras是美国思科（Cisco）公司的网络设备一款视频监控摄像头。 Cisco Video Surveillance 7000 存在安全漏洞，该漏洞源于思科视频监控7000系列IP摄像机链路层发现协议(LLDP)实现中的多个漏洞可能会存在内存泄漏，从而导致受影响设备的拒绝服务(DoS)条件。攻击者可利用该漏洞可以通过向受影响的设备发送精心制作的LLDP报文导致受影响的设备持续消耗内存。
