CVE-2005-3945 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 12.26% chance of exploitation in the next 30 days.
