Apple warns of security flaw that allows hackers to access devices

Apple has advised its users to immediately update their iPhones, iPods, and Macs to protect against a pair of security vulnerabilities that can allow hackers to take complete control of their devices.

One of the weaknesses affects the kernel, the deepest layer of the operating system that all the devices have in common, Apple said, while the other affects WebKit, the underlying technology of the Safari web browser.

Apple noted that it was “aware of a report that this issue may have been actively exploited,” crediting an anonymous researcher or researchers for disclosing both vulnerabilities.
