Apple has released a new software update that should fix a bug that made it possible to get past an iPhone lockscreen and access the device's phone functions, the company said.
The flaw, discovered last month, gave anyone access to a locked iPhone's photo library and contacts list by pressing on the power button and using the phone's emergency call option.
From the contacts list, users can send emails, text messages and make FaceTime calls, making the flaw particularly troubling. The update is rolling out to iPhone users, and should be available to all those affected by the bug. Users should upgrade their operating systems as soon as possible to protect their devices.
ZDNet noted earlier this month that a similar flaw exists for the Samsung Galaxy S III, that also gives anyone access to a locked device using the emergency call and power buttons. Samsung said on its company blog that it will be releasing its own update "shortly."
Apple owners should receive word of an update automatically from a pop-up message on their phones, but can also check for system updates in the "General" menu of their phones or by connecting to iTunes.
