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.
CVE-2002-0649
Score elevated to 9.0 because EPSS predicts 86% probability of exploitation within the next 30 days (top 0.6% of all CVEs). Confidence: see factors.
- High exploitation likelihood — EPSS 85%
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
