Microsoft Office Access Connectivity Engine Remote Code Execution Vulnerability

A vulnerability in Microsoft Office's Access Connectivity Engine allows an attacker to execute malicious code on a computer by tricking a user into opening a specially crafted file. This can lead to complete system compromise.

The vulnerability exists in the Access Connectivity Engine component when processing malformed database files or queries. An attacker can craft a malicious Office document that triggers unsafe code execution during file parsing, bypassing security boundaries and achieving arbitrary code execution in the user's security context.
