Remote code execution via malicious server response
Published Apr 9, 2024 · Updated May 3, 2025
Heap-based buffer overflow in affected Microsoft OLE DB Driver for SQL Server builds allows remote attackers to execute code via server data. The client connects to a malicious SQL Server and writes attacker-controlled response data beyond heap-buffer bounds; Microsoft has not disclosed the exact parser or buffer operation. User interaction is required to make the client connect, after which successful exploitation executes code in the client process context.

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 <16.0.1115.1
- Affected versionversion=16.0.0 <16.0.4120.1
