#### **1.0 Introduction**
Microsoft has released 12 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 Microsoft Security Bulletins MS15-124 through MS15-135 and apply the necessary updates.
**2.0 The list of the Important vulnerabilities is as below:**
> **2.1    Cumulative Security Update for Internet Explorer (3116180)**
> 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=699422>
>
> **2.2    Cumulative Security Update for Microsoft Edge (3116184)**
> 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=699426>
>
> **2.3   Cumulative Security Update for JScript and VBScript to Address Remote Code Execution (3116178)**
> 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.
> **Patch:** <http://go.microsoft.com/fwlink/?LinkId=699421>
>
> **2.4    Security Update for Microsoft Windows DNS to Address Remote Code Execution (3100465)**
> This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if an attacker sends specially crafted requests to a DNS server.
> **Patch:** <http://go.microsoft.com/fwlink/?LinkId=699414>
>
> **2.5    Security Update for Microsoft Graphics Component to Address Remote Code Execution (3104503)**
> This security update resolves vulnerabilities in Microsoft Windows, .NET Framework, Microsoft Office, Skype for Business, Microsoft Lync, and Silverlight. The vulnerabilities could allow remote code execution if a user opens a specially crafted document or visits a webpage that contains specially crafted embedded fonts.
> **Patch**: <http://go.microsoft.com/fwlink/?LinkId=690559>
>
> **2.6    Security Update for Silverlight to Address Remote Code Execution (3106614)**
> This security update resolves vulnerabilities in Microsoft Silverlight. The most severe of the vulnerabilities could allow remote code execution if Microsoft Silverlight incorrectly handles certain open and close requests that could result in read- and write-access violations. To exploit the vulnerability, an attacker could host a website that contains a specially crafted Silverlight application and then convince a user to visit a compromised website. The attacker could also take advantage of websites containing specially crafted content, including those that accept or host user-provided content or advertisements.
> **Patch:** <http://go.microsoft.com/fwlink/?LinkId=691214>
>
> **2.7    Security Update for Microsoft Uniscribe to Address Remote Code Execution (3108670)**
> This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user opens a specially crafted document or visits an untrusted webpage that contains specially crafted fonts.
> **Patch:** <http://go.microsoft.com/fwlink/?LinkId=690565>
>
> **2.8Security Update for Microsoft Office to Address Remote Code Execution (3116111)**
> This security update resolves vulnerabilities in Microsoft Office. The most severe of 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.
> **Patch:** <http://go.microsoft.com/fwlink/?LinkId=699410>
>
> **2.9Security Update for Microsoft Windows to Address Remote Code Execution (3116162)**
> This security update resolves vulnerabilities in Microsoft Windows. The vulnerabilities could allow remote code execution if an attacker accesses a local system and runs a specially crafted application.
> **Patch:** <http://go.microsoft.com/fwlink/?LinkId=699415>
>
> **2.10Security Update for Windows PGM to Address Elevation of Privilege (3116130)**
> This security update resolves vulnerabilities in Microsoft Windows. The more severe of the vulnerabilities could allow remote code execution if Windows Media Center opens a specially crafted Media Center link (.mcl) file that references malicious code. An attacker who successfully exploited this vulnerability 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=699419>
>
> **2.11Security Update for Windows Media Center to Address Remote Code Execution (3108669)** 
> This security update resolves vulnerabilities in Microsoft Windows. The more severe of the vulnerabilities could allow remote code execution if Windows Media Center opens a specially crafted Media Center link (.mcl) file that references malicious code. An attacker who successfully exploited this vulnerability 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=699419>
>
> **2.12 Security Update for Windows Kernel-Mode Drivers to Address Elevation of Privilege (3119075)**
> This security update resolves vulnerabilities in Microsoft Windows. The vulnerabilities could allow elevation of privilege if an attacker logs on to a target system and runs a specially crafted application.
> **Patch:** <http://go.microsoft.com/fwlink/?LinkId=708239>
