San Francisco (CNN Business) Apple has fixed the FaceTime bug that let people eavesdrop on unanswered group video calls.

The software updates -- iOS 12.1.4 and macOS Mojave 10.14.3 -- were rolled out to iPhones, iPads and Mac computers on Thursday, nine days after videos of the bug in action went viral on social media.

A person could exploit the glitch to hear live audio on another other person's phone, even though the recipient had not accepted the FaceTime call. In some cases, the bug could also show live video of the other person if they pressed a volume button to dismiss the call.

Apple said it will compensate 14-year-old Grant Thompson and his family for flagging the bug more than a week before it attracted national attention. The company, which didn't reveal how much the reward would be, said it will also contribute money toward his education.

While investigating the bug, Apple discovered another security issue involving Live Photos on FaceTime. The company did not specify what the bug was or how it worked, but the new updates fixes that issue. Apple disabled the use of LivePhotos in FaceTime on devices that have not yet been updated.
