MS16-053: Description of the security update for JScript and VBScript 5.7: May 10, 2016

Summary
This security update resolves vulnerabilities in the JScript and VBScript scripting engines in Microsoft Windows. The vulnerabilities could allow remote code execution if a user visits a specially crafted website. An attacker who successfully exploits these vulnerabilities could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploits these vulnerabilities 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.

To learn more about the vulnerability, see Microsoft Security Bulletin MS16-053.
