CVE-2005-3945

High
Published: Translated: NVD NIST

Summary

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.

Risk Assessment

The organization is at risk of server CPU exhaustion, potentially leading to network service unavailability for users.

Recommendation

Immediately install Service Pack 1 for Windows 2003 or Service Pack 4 for Windows 2000 to remediate the vulnerability.
