The License Logging service for Windows NT Server, Windows 2000 Server, and Windows Server 2003 does not properly validate the length of messages, which leads to an "unchecked buffer" and allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code, aka the "License Logging Service Vulnerability."

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."
