<p>A remote code execution vulnerability exists in the Microsoft JET Database Engine.</p> <p>An attacker who successfully exploited this vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.</p> <p>To exploit the vulnerability, a user must open/import a specially crafted Microsoft JET Database Engine file. In an email attack scenario, an attacker could exploit the vulnerability by sending a specially crafted file to the user, and then convince the user to open the file.</p> <p>The security update addresses the vulnerability by modifying how the Microsoft JET Database Engine handles objects in memory.</p>
