Vulnerability Description
The SYN cache (syncache) and SYN cookie (syncookie) mechanism in FreeBSD 4.5 and earlier allows remote attackers to cause a denial of service (crash) (1) via a SYN packet that is accepted using syncookies that causes a null pointer to be referenced for the socket's TCP options, or (2) by killing and restarting a process that listens on the same socket, which does not properly clear the old inpcb pointer on restart.

FreeBSD 4.5 syncache/syncookies拒绝服务攻击漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
FreeBSD是开放源代码的操作系统，其中FreeBSD 4.5支持了SYN cache (syncache)和SYN cookies (syncookies)机制，提供对FLOOD拒绝服务攻击的保护功能。 当syncookie实现时syncache会触发两个漏洞，可以导致系统崩溃。 1)当通过syncookie接收到SYN信息包时，它使用未初始化的指针来为新的套接口查找TCP选项，这个指针可以为NULL指针，这就可以导致系统崩溃。 2)当SYN信息包到达一监听套接口的时候会建立一syncache条目，如
