Code execution via unchecked stack buffer copy
Published Apr 15, 2020 · Updated Aug 4, 2024
Stack-based buffer overflow in the Microsoft Windows Jet Database Engine allows attackers to execute code through a crafted database file. The engine copies user-supplied data into a stack-based buffer without first validating its length, allowing the copy to corrupt control data. A target must visit a malicious page or open a malicious file, and successful exploitation runs code in the context of the current process.

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.
