Apple prohibits older versions of Adobe Flash Player in Safari

Apple revealed that they've restructured the web plug-in-blocking mechanism in Safari on OS X to deactivate older versions of the Adobe Flash Player, reports CNET. The move is a way to defend customers from a recent susceptibility that took advantage of an older version of the Flash Player plug-in.

To block older versions of Flash, Apple has updated its "Xprotect.plist" file so that any versions prior to the present one cannot be used on a Mac. Users who have older versions of Flash installed will receive an alert that says "Blocked plug-in," and Safari will prompt the user to update to a newer version. If you want to check which version of Flash you have installed right now, you can go to Adobe's website to get the version number and perform an update if necessary.
