[原文]The SynAttackProtect protection in Microsoft Windows 2003 before SP1 and Windows 2000 before SP4 with Update Roll-up uses a hash of predictable data, which allows remote attackers to cause a denial of service (CPU consumption) via a flood of SYN packets that produce identical hash values, which slows down the hash table lookups.


[CNNVD]Microsoft Windows SynAttackProtect 可预测Hash远程拒绝服务漏洞(CNNVD-200512-008)

        具有 Update Roll-up 的Microsoft Windows 2003 SP1之前版本和 Windows 2000 SP4之前版本的SynAttackProtect 保护采用了可预测数据的 hash。远程攻击者可以借助可产生相同hash值的大量SYN数据包,减慢hash表查询速度,从而造成拒绝服务(CPU消耗)。
