Apple has issued a critical security update for Mac OS X users, plugging a Network Time Protocol (NTP) security hole that left users open to cyberattacks. The automated security update had a quick turnaround because cybercriminals could have gained remote access of machines through by exploiting the bug, according to researchers.
The US Department of Homeland Security and Carnegie Mellon University Software Engineering Institute recently flagged the bugs, and Apple scrambled to create a fix ahead of the holidays. Carnegie Mellon also found that dozens of companies are vulnerable to the same type of security bug, which should be fixed sooner rather than later.
Here is what Apple's support page notes: "The update addresses a critical security issue with the software that provides the Network Time Protocol service on OS X, and is recommended for all users. For more information on the security content of this update see: http://support.apple.com/kb/HT1222."
