**1.0 Introduction**
Microsoft has released 9 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.
**2.0 The list of the Important vulnerabilities are as below:**
2.1 Cumulative Security Update for Internet Explorer (3177356)
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 this vulnerability 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 this vulnerability 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=821136](http://go.microsoft.com/fwlink/?LinkId=821136 )
2.2 Cumulative Security Update for Microsoft Edge (3177358)
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=821137>
2.3 Security Update for Microsoft Graphics Component (3177393)
This security update resolves vulnerabilities in Microsoft Windows, Microsoft Office, Skype for Business, and Microsoft Lync. The vulnerabilities could allow remote code execution if a user either visits a specially crafted website or opens a specially crafted document. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
• Patch: <http://go.microsoft.com/fwlink/?LinkId=821146>
2.4 Security Update for Windows Kernel-Mode Drivers (3178466)
This security update resolves vulnerabilities in Microsoft Windows. The vulnerabilities could allow elevation of privilege if an attacker logs on to an affected system and runs a specially crafted application that could exploit the vulnerabilities and take control of an affected system.
• Patch: <http://go.microsoft.com/fwlink/?LinkId=821582>
2.5 Security Update for Microsoft Office (3177451)
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=821165>
2.6 Security Update for Secure Boot (3179577)
This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow security feature bypass if an attacker installs an affected boot manager and bypasses Windows security features.

2.8 Security Update for Microsoft Windows PDF Library (3182248)
This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user views specially crafted PDF content online or opens a specially crafted PDF document. An attacker who successfully exploited the vulnerability 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=823207>
