On Dec 28th, 2015 Adobe released a security update for Adobe Flash Player to address
what they describe as “critical vulnerabilities” that allow an attacker to take control of the affected system. Microsoft released security advisory
2755801 and security update
KB3132372 to make the updated Adobe Flash Player available to all users.
Adobe and Microsoft are aware of reports of some application crashes after installing this update and are researching this problem. We will post additional information in this thread and in KB3132372 under the More Information section.
Microsoft does not recommend uninstalling KB3132372 as has been suggested in several forum posts and we don’t recommend blocking the update from installing. Both of these steps would leave any system that is connected to the internet vulnerable to the exploit detailed by Adobe and Microsoft.
Update (1/5/16) - On January 5th, Microsoft released an update (KB3133431) for Internet Explorer 11 on Windows 10 and Microsoft Edge on Windows 10. The update addresses some application compatibility issues introduced in update KB3132372 as well as the vulnerabilities described in Adobe Security bulletin APSB16-01. For more information about this update, including download links, see Microsoft Knowledge Base Article 3133431. For Windows 10 users, both this update and update KB3132372 will be offered and installed.
