Remote code execution via crafted file handling
Published Oct 8, 2024 · Updated Aug 19, 2026
A heap-based buffer overflow in Microsoft ActiveX Data Objects on affected Windows releases allows remote attackers to execute code. Microsoft identifies the component and weakness class but has not published the affected function or the operation that overruns heap memory. Exploitation requires a user to open a crafted malicious file, after which attacker-controlled code runs in that user'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=10.0.10240.0 <10.0.10240.20796
