We often publish articles about Flash Player security alerts and updates, warning users to update their version of the Flash Player plugin, which can be a vector for remote attacks on their computers. The current version of Flash Player for Mac is 10.0.32.18, but if you go to the Flash Player version test page after installing Snow Leopard, you’ll find that you have version 10.0.23.1, even if you were up-to-date before the upgrade. It seems that Apple is shipping an outdated, even dangerous version of Flash Player.
We therefore recommend that you go to Adobe’s Flash Player download page and grab a copy of the latest version and update your Mac. This one’s been out for a while; there’s no reason why Apple should be shipping an old version.
