Detail

Severity Rating: Critical
Revision Note: V1.1 (May 25, 2016): Removed redundant rows from the Vulnerability Severity Rating and Maximum Security Impact by Affected Software table, and added the applicable update numbers for clarity. This is an informational change only.
Summary: This security update resolves vulnerabilities in the VBScript scripting engine in Microsoft Windows. The more severe of the vulnerabilities could allow remote code execution if an attacker hosts a specially crafted website that is designed to exploit the vulnerabilities through Internet Explorer (or leverages a compromised website or a website that accepts or hosts user-provided content or advertisements) and then convinces a user to view the website. An attacker could also embed an ActiveX control marked "safe for initialization" in an application or Microsoft Office document that uses the Internet Explorer rendering engine to direct the user to the specially crafted website.
