Vulnerability Description
The TCP MSS (maximum segment size) functionality in netinet allows remote attackers to cause a denial of service (resource exhaustion) via (1) a low MTU, which causes a large number of small packets to be produced, or (2) via a large number of packets with a small TCP payload, which cause a large number of calls to the resource-intensive sowakeup function.

FreeBSD NetINet TCP MSS大小远程拒绝服务漏洞
Vulnerability Description
FreeBSD是一款开放源代码的操作系统。 FreeBSD netinet实现对TCP MSS处理存在问题，远程攻击者可以利用这个漏洞对目标进行拒绝服务攻击。 为了网络连接优化，TCP需要调整MSS，然后包大小必须遵守路径MTU，这可以通过动态的从远程主机和网络的反馈进行调整。 要进行资源耗竭，可通过如下两种方法： - TCP连接阶段设置通告在末端间交换的本地MSS，远程末端可以设置任意低的MSS值(除了BSD代码强制限制的64八位组的最小MTU)。当本地主机发送数据会强制发送个小的IP包来代替大包。 如
