The WINS service (wins.exe) on Microsoft Windows NT Server 4.0, Windows 2000 Server, and Windows Server 2003 allows remote attackers to write to arbitrary memory locations and possibly execute arbitrary code via a modified memory pointer in a WINS replication packet to TCP port 42, aka the "Association Context Vulnerability."
CVE-2004-1080
Score elevated to 9.0 because EPSS predicts 89% probability of exploitation within the next 30 days (top 0.4% of all CVEs). Confidence: see factors.
