Cisco IOS特制TCP报文远程拒绝服务漏洞

Cisco IOS是Cisco设备所使用的操作系统。 Cisco IOS在处理特定畸形的TCP报文时存在漏洞，远程攻击者可能利用此漏洞对设备执行拒绝服务攻击，导致设备耗尽所有内存无法正常工作。 如果将Cisco IOS设备配置为接收TCP报文的话，则发送给Cisco IOS设备物理或虚拟接口IPv4地址的特制报文就可能导致泄漏少量的内存。这种内存泄漏可能造成耗尽内存资源，降低系统的性能。 请注意攻击者无需完成TCP三重握手就可以触发这个漏洞，因此伪造源址的TCP报文也可以完成攻击。这个漏洞仅适用于目标为Cisco IOS设备的通讯，穿越Cisco IOS设备的通讯不会触发这个漏洞。...
