Earlier this month, Apple released an update that was supposed to patch a serious flaw in OS X, albeit only for Yosemite users. But, according to a recent finding by an independent researcher, the company from Cupertino failed to fix the problem. Objective-See, a website that provides tools to prevent OS X malware, reports that the backdoor security flaw, known as "RootPipe," can still be exploited. The root access vulnerability is a major one too, as it could give anyone with bad intentions a way to take over a user's machine and, if they want, inject malware into the operating system. We've reached out to Apple for comment and will be updating this story if and when it gets back to us.
