Remote code execution via heap buffer overflow
Published Apr 9, 2024 · Updated May 3, 2025
Heap-based buffer overflow in Microsoft OLE DB Driver for SQL Server allows remote attackers to execute code via malicious server data. The driver processes data returned by a malicious SQL Server and overwrites a heap buffer, but Microsoft has not disclosed the affected routine or input field. Exploitation requires an authenticated user to initiate the connection; successful exploitation executes arbitrary code on that user's client.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=16.0.0 <16.0.4120.1
