Adobe released an update to Flash Player today. This one comes just two weeks after the last update. The full Adobe security bulletin can be found here. As always you can update your version of Flash Player by going to System Preferences > Flash Player > Advanced and update from there or you can download the latest version directly from the Adobe website. After updating your version should be: 18.104.22.168
The vulnerabilities that were addressed are already being exploited in the wild so it is important to install the update as soon as possible.
