Remote code execution via heap buffer overflow
Published Nov 12, 2024 · Updated Jul 8, 2025
Heap-based buffer overflow in Microsoft SQL Server Native Client allows remote attackers to execute code after user interaction. The documented defect is a heap-based buffer overflow in the Native Client, but Microsoft has not identified the affected parser, input field, or erroneous memory operation. Exploitation requires a user or user-initiated process to interact with attacker-controlled network content; successful execution runs in that process's security 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=13.0.0 <13.0.7055.9
