#### **1.0 Introduction**
#### Microsoft has released eight updates to address vulnerabilities in Microsoft Windows. Exploitation of some of these vulnerabilities could allow remote code execution or elevation of privileges. Users and administrators are encouraged to review Microsoft Security Bulletins MS15-056 through - MS15-064 and apply the necessary updates.
**2.0 The list of the Important vulnerabilities is as below:2.1    Cumulative Security Update for Internet Explorer (3058515)**
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 these 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=614953>
**2.2    Vulnerability in Windows Media Player Could Allow Remote Code Execution (3033890)**
This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if Windows Media Player opens specially crafted media content that is hosted on a malicious website. An attacker who successfully exploited this vulnerability could take complete control of an affected system remotely. 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=614954>
**2.3   Vulnerabilities in Microsoft Office Could Allow Remote Code Execution (3064949)**
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=614957>
**2.4    Vulnerability in Microsoft Common Controls Could Allow Remote Code Execution (3059317)**
This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user clicks a specially crafted link, or a link to specially crafted content, and then invokes F12 Developer Tools in Internet Explorer.
**Patch:** <http://go.microsoft.com/fwlink/?LinkID=614958>
**2.5    Vulnerabilities in Windows Kernel-Mode Drivers Could Allow Elevation of Privilege (3057839)**
This security update resolves vulnerabilities in Microsoft Windows. The most severe of these vulnerabilities could allow elevation of privilege if an attacker logs on to the system and runs a specially crafted application. 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=614959>
**2.6    Vulnerability in Active Directory Federation Services Could Allow Elevation of Privilege (3062577)**
This security update resolves a vulnerability in Microsoft Active Directory Federation Services (AD FS). The vulnerability could allow elevation of privilege if an attacker submits a specially crafted URL to a target site. Due to the vulnerability, in specific situations specially crafted script is not properly sanitized, which subsequently could lead to an attacker-supplied script being run in the security context of a user who views the malicious content. For cross-site scripting attacks, this vulnerability requires that a user be visiting a compromised site for any malicious action to occur.
**Patch:** <http://go.microsoft.com/fwlink/?LinkID=614960>
**2.7    **Vulnerability in Windows Kernel Could Allow Elevation of Privilege (3063858)**
This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if an attacker places a malicious .dll file in a local directory on the machine or on a network share. An attacker would then have to wait for a user to run a program that can load a malicious .dll file, resulting in elevation of privilege. However, in all cases an attacker would have no way to force a user to visit such a network share or website.
**Patch:** <http://go.microsoft.com/fwlink/?LinkID=614961>
**2.8    Vulnerabilities in Microsoft Exchange Server Could Allow Elevation of Privilege (3062157)**
This security update resolves vulnerabilities in Microsoft Exchange Server. The most severe of the vulnerabilities could allow elevation of privilege if an authenticated user clicks a link to a specially crafted webpage. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to click a link, typically by way of an enticement in an email or Instant Messenger message.
**Patch:** <http://go.microsoft.com/fwlink/?LinkID=614962>
**3.0    Recommendation**
Users and administrators are recommended to perform the update immediately. All of the patches could be done almost automatically via the Windows Update application.
