Multiple buffer overflows in the Resolution Service for Microsoft SQL Server 2000 and Microsoft Desktop Engine 2000 (MSDE) allow remote attackers to cause a denial of service or execute arbitrary code via UDP packets to port 1434 in which (1) a 0x04 byte that causes the SQL Monitor thread to generate a long registry key name, or (2) a 0x08 byte with a long string causes heap corruption, as exploited by the Slammer/Sapphire worm.

Security readout for executives and security teams

This is a wormable flaw in Microsoft SQL Server 2000 and MSDE 2000. A remote attacker could send malformed UDP traffic to the SQL Resolution Service on port 1434, causing denial of service or arbitrary code execution. It was historically exploited by the Slammer/Sapphire worm, so any surviving exposed legacy instance deserves urgent attention. Exposure is limited to legacy Microsoft SQL Server 2000 or MSDE 2000 systems, including embedded MSDE installations, with the Resolution Service reachable over UDP 1434. Internet-facing or broadly reachable internal instances are the highest-risk cases. Treat exposed legacy instances as urgent. The business risk is not theoretical: this class of flaw enabled a major worm outbreak. Prioritize discovery, isolation, and retirement because unsupported legacy database services often remain hidden inside older applications. Mitigation focus: Apply Microsoft MS02-039 or later applicable vendor guidance for SQL Server 2000/MSDE 2000.; Block or tightly restrict UDP 1434 from untrusted networks.; Identify embedded MSDE 2000 instances shipped with third-party products..
