Maximum Severity Rating
and Vulnerability Impact

MS16-051

Cumulative Security Update for Internet Explorer (3155533)
This security update resolves vulnerabilities in Internet Explorer. The most severe of the vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker who successfully exploited the vulnerabilities could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker 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.

Critical
Remote Code Execution

MS16-052

Cumulative Security Update for Microsoft Edge (3155538)
This security update resolves vulnerabilities in Microsoft Edge. The most severe of the vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Microsoft Edge. An attacker who successfully exploited the vulnerabilities could gain the same user rights as the current user. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than users with administrative user rights.

Critical
Remote Code Execution

MS16-053

Cumulative Security Update for JScript and VBScript (3156764)
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 exploited 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 exploited 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.

Critical
