Microsoft Security Updates for September, 2017

The September security release consists of 81 security updates for the following software in which 26 are listed as Critical, 53 are rated Important, and two are Moderate in severity. 

• Internet Explorer
• Microsoft Edge
• Microsoft Windows
• Microsoft Office and Microsoft Office Services and Web Apps
• Adobe Flash Player
• Skype for Business and Lync
• .NET Framework
• Microsoft Exchange Server

The updates address Remote Code Execution, Spoofing, "Defense in Depth", Information Disclosure and Elevation of Privilege. "Defense-in-Depth" is a fix that does not apply to an actively exploitable vulnerability but prevents future vulnerabilities caused by the same code when surrounding code changes expose the problem.

For more information about the updates released today, see https://portal.msrc.microsoft.com/en-us/security-guidance/summary.  Updates can be sorted by OS from the search box. Information about the update for Windows 10 is available at Windows 10 Update history.
