漏洞描述
中文描述:
Cisco ASR 9000是美国思科（Cisco）公司的一款9000系列聚合服务路由器。 Cisco ASR 9000存在安全漏洞，攻击者可利用该漏洞可以通过慢路径转发触发致命错误，以触发拒绝服务。
英文描述:
A vulnerability in the ingress packet processing function of Cisco IOS XR Software for Cisco ASR 9000 Series Aggregation Services Routers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper resource allocation when an affected device processes network traffic in software switching mode (punted). An attacker could exploit this vulnerability by sending specific streams of Layer 2 or Layer 3 protocol data units (PDUs) to an affected device. A successful exploit could cause the affected device to run out of buffer resources, which could make the device unable to process or forward traffic, resulting in a DoS condition. The device would need to be restarted to regain functionality.
