#### **1.0 Introduction**
Microsoft has released 16 updates to address vulnerabilities in Microsoft software. Exploitation of some of these vulnerabilities could allow a remote attacker to take control of an affected system. Users and administrators are encouraged to review the following Microsoft Security Bulletins MS16-051 through MS16-067 and apply the necessary updates.
**2.0 The list of the Important vulnerabilities is as below:**
> **2.1    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**.**
> **Patch:** <http://go.microsoft.com/fwlink/?LinkId=785873>
>
> **2.2    **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.
> **Patch:** <http://go.microsoft.com/fwlink/?LinkId=785874>
>
> **2.3   **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.
> **Patch:** <http://go.microsoft.com/fwlink/?LinkId=786478>
>
> **2.4    **Security Update for Microsoft Office (3155544)**
> This security update resolves vulnerabilities in Microsoft Office. The vulnerabilities could allow remote code execution if a user opens a specially crafted Microsoft Office file. An attacker who successfully exploited the vulnerabilities could run arbitrary code in the context of the current user. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
