BUGTRAQ ID: 31356 CVE ID: CVE-2008-3808 CVE-2008-3809 CNCVE ID:CNCVE-20083808 CNCVE-20083809

Cisco IOS PIM是支持网络中的IP组播路由,允许网络接收所请求的组播流量的协议实现。 Cisco IOS软件处理特殊构建的PIM报文存在问题,可导致拒绝服务攻击。运行Cisco IOS软件和配置了PIM的设备受第一个漏洞影响,配置为PIM的Cisco 12000 Series (GSR)路由器受第二个漏洞影响。 Cisco IOS设备上的PIM模式包含密集,稀疏和稀疏-密集模式,模式用于判断设备怎样统计它的多播路由表和怎样转发多播报文。必须在设备上启用其中一个模式来执行IP组播路由。 注意:没有默认的模式设置,默认条件下,组播路由在接口上禁用。 要在接口上启用密集模式的PIM,使用如下配置命令: Router(config-if)# ip pim dense-mode 要在接口上启用稀疏模式的PIM,使用如下配置命令: Router(config-if)# ip pim sparse-mode 要在接口上启用稀疏-密集模式的PIM,使用如下配置命令: Router(config-if)# ip pim sparse-dense-mode Cisco bug ID CSCsd95616-特殊构建的PIM可导致IOS设备重载。 Cisco bug ID CSCsl34355-畸形的PIM报文可导致GSR崩溃。 CVE ID为CVE-2008-3808和CVE-2008-3809。
