7.8 HIGH — AV:N/AC:L/Au:N/C:N/I:N/A:C

Description

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.

Affected configurations

• microsoft windows 2000 • microsoft windows 2003 server enterprise • microsoft windows 2003 server r2 • microsoft windows 2003 server standard • microsoft windows 2003 server web
