CVE-2020-3566 (CNNVD-202008-1423)
中文标题:
Cisco IOS和Cisco IOS XR 资源管理错误漏洞
英文标题:
Cisco IOS XR Software DVMRP Memory Exhaustion Vulnerability
漏洞描述
中文描述:
Cisco IOS和Cisco IOS XR都是美国思科（Cisco）公司的一套为其网络设备开发的操作系统。 Cisco IOS XR Software中的DVMRP存在安全漏洞，该漏洞源于Internet组管理协议（IGMP）数据包的队列管理不足造成的，攻击者可以通过向受影响的设备发送精心编制的IGMP数据包来进行攻击。
英文描述:
A vulnerability in the Distance Vector Multicast Routing Protocol (DVMRP) feature of Cisco IOS XR Software could allow an unauthenticated, remote attacker to exhaust process memory of an affected device. The vulnerability is due to insufficient queue management for Internet Group Management Protocol (IGMP) packets. An attacker could exploit this vulnerability by sending crafted IGMP traffic to an affected device. A successful exploit could allow the attacker to cause memory exhaustion, resulting in instability of other processes. These processes may include, but are not limited to, interior and exterior routing protocols. Cisco will release software updates that address this vulnerability.
