Bonus post about that Adobe Flash vulnerability, which as of today is all fixed up. The version to see is 18.0.0.203, or 18.0.0.204 for Linux.
If you have Chrome, do not use Adobe’s site to update Flash. Chrome has Flash built in and the plugin is updated along with Google’s updates. Check to see if you are running version 43.0.2357.132 in the about page, which contains the fixed plugin.
If so, it’s safe to reenable Flash.
