中文标题:
Cisco Video Surveillance 7000 Series IP Cameras 资源管理错误漏洞
英文标题:
Cisco Video Surveillance 7000 Series IP Cameras Link Layer Discovery Protocol Double-Free Denial of Service Vulnerability
漏洞描述
中文描述:
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 系列 IP 摄像机固件的链路层发现协议 (LLDP) 实施中存在资源管理错误漏洞,该漏洞源于内存资源管理不当。该漏洞可能允许未经身份验证的相邻攻击者导致拒绝服务 (DoS) 条件。
英文描述:
A vulnerability in the Link Layer Discovery Protocol (LLDP) implementation for the Cisco Video Surveillance 7000 Series IP Cameras firmware could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition. This vulnerability is due to improper management of memory resources, referred to as a double free. An attacker could exploit this vulnerability by sending crafted LLDP packets to an affected device. A successful exploit could allow the attacker to cause the affected device to 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).
