Today is the August 2016 Microsoft Patch Tuesday and we have nine security updates being released by Microsoft. Of these nine updates, five of them are rated as Critical as they allow remote code execution on the affected computer.

Remote Code Execution vulnerabilities are ones that allow an attacked to remotely execute commands on a computer. These commands could download further software, add user accounts, or perform virtual any action on the vulnerable computer.

All Windows users should immediately run Windows update and install all of the available updates as soon as possible. For a full list of the updates, vulnerabilities, and links to their respective bulletins, please see the table below.

August 2016 Windows Security Updates:

MS16-095 Cumulative Security Update for Internet Explorer (KB3177356)

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.

This security update is rated Critical for Internet Explorer 9 (IE 9), and Internet Explorer 11 (IE 11) on affected Windows clients, and Moderate for Internet Explorer 9 (IE 9), Internet Explorer 10 (IE 10), and Internet Explorer 11 (IE 11) on affected Windows servers. 

MS16-096 Cumulative Security Update for Microsoft Edge (KB3177358)

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.

This security update is rated Critical for Microsoft Edge on Windows 10.

MS16-097 Security Update for Microsoft Graphics Component (KB3177393)

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.

This security update is rated Critical for:

  • All supported releases of Microsoft Windows
  • Affected editions of Microsoft Office 2007 and Microsoft Office 2010
  • Affected editions of Skype for Business 2016, Microsoft Lync 2013, and Microsoft Lync 2010

The security update addresses the vulnerabilities by correcting how the Windows font library handles embedded fonts. 

MS16-098 Security Update for Windows Kernel-Mode Drivers (KB3178466)

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.

This security update is rated Important for all supported releases of Windows.

MS16-099 Security Update for Microsoft Office (KB3177451)

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.

This security update is rated Critical.
