中文描述:

Cisco Aggregation Services Router（ASR）5000 Series Routers和Virtualized Packet Core（VPC）System Software都是美国思科（Cisco）公司的产品。Cisco Aggregation Services Router（ASR）5000 Series Routers是一款5000系列的安全路由器设备。Virtualized Packet Core（VPC）System Software是一套被部署在专用硬件平台的StarOS软件的产品化版本。StarOS是使用在其中的一套操作系统。IPsec Manager是其中的一个IPsec管理器。 Cisco ASR 5000 Series Routers和VPC System Software上的StarOS的IPsec Manager存在资源管理错误漏洞，该漏洞源于程序没有正确的处理损坏的互联网密钥交换协议2版本（IKEv2）消息。远程攻击者可通过发送特制的IKEv2消息利用该漏洞终止任意活动的IPsec VPN通道并阻止新的IPsec VPN通道建立。

英文描述:

A vulnerability in the IPsec Manager of Cisco StarOS for Cisco Aggregation Services Router (ASR) 5000 Series Routers and Virtualized Packet Core (VPC) System Software could allow an unauthenticated, remote attacker to terminate all active IPsec VPN tunnels and prevent new tunnels from being established, resulting in a denial of service (DoS) condition. The vulnerability is due to improper processing of corrupted Internet Key Exchange Version 2 (IKEv2) messages. An attacker could exploit this vulnerability by sending crafted IKEv2 messages toward an affected router. A successful exploit could allow the attacker to cause the ipsecmgr service to reload. A reload of this service could cause all IPsec VPN tunnels to be terminated and prevent new tunnels from being established until the service has restarted, resulting in a DoS condition. This vulnerability affects the following Cisco products when they are running Cisco StarOS: Cisco Aggregation Services Router (ASR) 5000 Series Routers, Virtualized Packet Core (VPC) System Software. Cisco Bug IDs: CSCve29605.
