Earlier today Adobe released updates for Flash Player, Adobe Reader, Acrobat and Shockwave Player. The latest versions can be obtained through the links below or through the Adobe Updaters in the actual products.
Apple has updated OS X’s XProtect list and has blocked all Flash Player versions prior to 11.8.800.94 so if you find Flash content is not working, make sure you have the latest version installed. Again, this can be done through the above link or by going to your System Preferences > Flash Player > Advanced > Check Now. Older versions of Adobe Reader and Shockwave are not blocked but it is recommended you update these products. This ensures you are not vulnerable if someone attempts to exploit bugs or vulnerabilities in the older versions.
Acrobat updates can also be obtained by launching the application, then clicking the Help menu and selecting ‘Check for Updates’.
