#### **1.0 Introduction**
Microsoft has released twelve updates to address vulnerabilities in Microsoft Windows. Exploitation of some of these vulnerabilities could allow an attacker to take control of an affected system. Users and administrators are encouraged to review Microsoft Security Bulletins MS15-112 through MS15-123 and apply the necessary updates.
**2.0 The list of the Important vulnerabilities is as below:**
> **2.1    Cumulative Security Update for Internet Explorer (3104517)**
>
> > 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. 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.
> > **Patch:** <http://go.microsoft.com/fwlink/?LinkId=690584>
>
> **2.2    Cumulative Security Update for Microsoft Edge (3104519**)**
>
> > 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 those who operate with administrative user rights.

> > **Patch:** <http://go.microsoft.com/fwlink/?LinkId=690588>
>
> **2.9Security Update for IPSec to Address Denial of Service (3102939)**
