[原文]Cisco IOS 2.2(18)EW, 12.2(18)EWA, 12.2(14)SZ, 12.2(18)S, 12.2(18)SE, 12.2(18)SV, 12.2(18)SW, and other versions without the "no service dhcp" command, keep undeliverable DHCP packets in the queue instead of dropping them, which allows remote attackers to cause a denial of service (dropped traffic) via multiple undeliverable DHCP packets that exceed the input queue size.


[CNNVD]Cisco IOS DHCP 拒绝服务漏洞(CNNVD-200501-136)

        Cisco IOS是Cisco网络设备所使用的系统。
        多个Cisco IOS版本( 2.2(18)EW, 12.2(18)EWA, 12.2(14)SZ, 12.2(18)S, 12.2(18)SE, 12.2(18)SV、12.2(18)SW和其他没有"no service dhcp"命令的版本)存在拒绝服务漏洞。
        由于上述版本中会将无法交付的DHCP包保留在队列中,而不是将其删除,这使得远程攻击者通过超过输入队列大小的多个无法交付的DHCP包造成系统拒绝服务(流量下降)。
