Just as it did with some versions of Java, Apple has now blocked older versions of Adobe's Flash plugin to protect Mac users from security risks. In a new support document posted to its website on Friday, Apple explained that it has already updated its plugin blocking tool built into Safari—users don't need to lift a finger.
"To help protect users from a recent vulnerability, Apple has updated the web plug-in-blocking mechanism to disable older versions of the web plug-in: Adobe Flash Player," the company wrote.
Earlier this year, Apple blacklisted the latest version of Java—twice—due to security vulnerabilities. But Flash comes with its own security risks: Adobe issued an emergency Flash update earlier this month due to similar vulnerabilities on OS X and Windows, with another emergency update issued again three days ago. Like the Java holes, the Flash vulnerabilities allow remote attackers to surreptitiously install malware on vulnerable machines.
