This will tell you if your computer is running an outdated version edition of Flash.
Software giant Adobe is urging Flash users to download a software patch after the discovery of flaw that could be exploited by hackers.
Adobe Flash is a plug-in used by browsers such as Internet Explorer and Google Chrome to play video content.
Two important notes: if you have selectively blocked or enabled Flash for particular websites you may need to adjust that list in order for Flash to load as intended, similarly if you use a plugin like Click To Flash in Safari you may want to disable that temporarily beforehand while you update Flash.
And obviously if you uninstalled it that is going to become undone by this process, so be mindful of that if you had a compelling reason to remove the plugin from Safari to begin with.
Mac users who primarily browse the web with Safari will eventually notice the “Flash out-of-date” message appearing somewhere in the browser.
This happens because the Mac will intentionally disable the Flash player plugin when it has become outdated, preventing any potential security breaches from occurring.
That’s what we’re aiming to address here, properly installing the latest version of Flash to get the plugin working again in Safari and to resolve that error message.
In a statement Adobe said the patch “addresses a critical vulnerability (CVE-2015-3113) that could potentially allow an attacker to take control of the affected system.
“Adobe is aware of reports that CVE-2015-3113 is being actively exploited in the wild via limited, targeted attacks.
For the past five years, the option to view You Tube content using HTML5 existed, but the default was Flash Player.
For the safety and security of your computer system, and also for the stability of web content you encounter that requires Adobe Flash Player, it is always best to update Flash Player to keep your installation current.
