Vulnerability Title
Cisco IOS XR MPLS拒绝服务漏洞
Vulnerability Description
Cisco IOS XR软件是Cisco IOS软件家族的成员，使用基于微内核的分布式操作系统基础架构。Cisco IOS XR运行在Cisco CRS-1和Cisco 12000系列路由器上。 Cisco CRS-1或12000系列系统交换的特殊MPLS报文会导致NetIO进程重启。如果NetIO进程连续几次重启，线卡就会重载，导致该线卡所交换的通讯拒绝服务。 MPLS报文通过MPLS网络转发，因此可以从MPLS网络中的远程系统发送触发这个漏洞的报文。无法在没有配置MPLS的接口上接收这样的报文。
