VOIP telephony company Skype has released an official update correcting a serious security issue in their most current version of Skype for Mac, a problem that could have been exploited by an attacker to remotely take control of the computer. New version 5.1.59.947, available directly from the company or through the program's own update mechanism, closed the security hole and also resolves other minor bugs, including an issue of video "freezing" in high packet-loss situations.
