Posted by Ahmed Nabil | 1 comments»
Recently users with EMET 4.1 installed on their machines started getting problems with Google Chrome. When users try to open Google Chrome they get an EMET Caller mitigation violation and Chrome crash and get closed. The Following event will be logged in the Application Event Viewer.

This issue started Late May, 2014 (20/21) after Google released the latest version of Chrome (35.0.1916.114). This issue was addressed on several other sites as Chromium http://www.chromium.org/Home/chromium-security/chromium-and-emet

as well as EMET Application compatibility Forum http://social.technet.microsoft.com/Forums/security/en-US/1e70c72b-67b2-43c4-bd36-a0edd1857875/application-compatibility-issues?forum=emet

The temporary Solution for this issue was to remove the Google Chrome from the list of Protected applications in EMET or disabling the caller mitigation for Chrome.exe.

Final Resolution:

Microsoft Released EMET 4.1 Update 1 on 29/5/2014 http://www.microsoft.com/en-eg/download/details.aspx?id=41138

This update added new functionality and updates which includes fixing this compatibility issue and other false positive reporting as per attached documentation.

After applying this update and rebooting the machine users were able to open the Chrome.exe without any problem.

Note: When applying this update make sure to keep your existing settings.
