EMET 5.1 is available

Security Research & Defense
/ By swiat /

Today, we’re releasing the Enhanced Mitigation Experience Toolkit (EMET) 5.1 which will continue to improve your security posture by providing increased application compatibility and hardened mitigations. You can download EMET 5.1 from microsoft.com/emet or directly from here. Following is the list of the main changes and improvements:

  • Several application compatibility issues with Internet Explorer, Adobe Reader, Adobe Flash, and Mozilla Firefox and some of the EMET mitigations have been solved.
  • Certain mitigations have been improved and hardened to make them more resilient to attacks and bypasses.
  • Added “Local Telemetry” feature that allows to locally save memory dumps when a mitigation is triggered.

All the changes in this release are listed in Microsoft KB Article 3015976.

If you are using Internet Explorer 11, either on Windows 7 or Windows 8.1, and have deployed EMET 5.0, it is particularly important to install EMET 5.1 as compatibility issues were discovered with the November Internet Explorer security update and the EAF+ mitigation. Alternatively, you can temporarily disable EAF+ on EMET 5.0. Details on how to disable the EAF+ mitigation are available in the User Guide. In general we recommend upgrading to the latest version of EMET to benefit from all the enhancements.

We want to particularly thank Luca Davi, Daniel Lehmann, and Ahmad-Reza Sadeghi from System Security Lab at Technical University Darmstadt/CASED, and René Freingruber form SEC Consult for partnering with us.

Your feedback is always welcome as it helps us improve EMET with each new release, so we encourage you to reach out using the Connect Portal or by sending an email to emet_feedback@microsoft.com.
