The License Logging Server (llssrv.exe) in Microsoft Windows 2000 SP4 allows remote attackers to execute arbitrary code via an RPC message containing a string without a null terminator, which triggers a heap-based buffer overflow in the LlsrLicenseRequestW method, aka "License Logging Server Heap Overflow Vulnerability."

Security readout for executives and security teams

This is an old Microsoft Windows 2000 SP4 flaw in the License Logging Server. A remote attacker could potentially run code on an affected system by sending a malformed RPC message. The business risk is mainly legacy exposure: any remaining Windows 2000 systems should be treated as high-risk assets. Exposure is most likely in legacy environments still running Microsoft Windows 2000 SP4 with License Logging Server reachable over RPC. The provided affected-product metadata is incomplete, so inventory confirmation is required. Treat as urgent only where legacy Windows 2000 remains in production. Remote code execution on obsolete systems can create disproportionate risk, especially if reachable from broader internal networks. Mitigation focus: Review Microsoft MS09-064 guidance for the official fix path.; Patch or retire affected Windows 2000 SP4 systems.; Restrict RPC access to trusted management networks only..
