ITS has posted a patch-level release of the UT Drupal Kit in order to address the critical security vulnerability in the Panels module announced on August 3, 2016 (View the security advisory on Drupal.org).
This module is included as part of the UT Drupal Kit distribution, but is not enabled by default. If you are using the UT Drupal Kit but have not enabled the Panels module on your own, you do not need to apply this update and can wait until our next release, which is currently scheduled for Tuesday, October 4, 2016.
How to Update the UT Drupal Kit
Complete instructions for updating a UT Drupal Kit site are available on the documentation wiki.
Please review the release notes thoroughly, and always make backups of your code, files, and database before proceeding with an update!
