While they were fixing the bug, they disabled Group FaceTime, so that the bug could not be abused.
In release notes for the update, Apple credits the discovery of the flaw to Grant Thompson of Catalina Foothills High School and Daven Morris of Arlington, Texas.
The bug allowed eavesdropping by someone calling their FaceTime contacts, receiving audio from them without their knowledge before they answered the call.
Apple said Thursday it will contribute to a teenager's college fund and pay a bounty to him and his family for discovering a software flaw that allowed people to eavesdrop on others while using FaceTime on iPhones. The arrival of the new version of iOS comes just two days after a pair of congressmen sent a letter (which you can read here) to CEO Tim Cook that included a list of questions they'd like him to answer in the wake of the bug.
The fix is included in the latest version of Apple's iOS 12 system, which became available to install Thursday.
Whitaker refuses to testify unless Democrats drop subpoena threat
Collins said that the Justice Department's response to the subpoena vote showed that Democrats "overplayed their hand". The vote by the House panel didn't issue a subpoena but allowed Nadler to do so if Whitaker was uncooperative.
Apple turned off the group-chat feature last week after a 14-year-old boy in Arizona discovered the flaw.
Apple did not immediately respond to requests for comment.
The update is about 335MB is size and you'll have to connect to a WiFi connection to download. So if you want Group FaceTime available for you on your supported devices, then you will want to make sure that you update to iOS 12.1.4 as quickly as possible. Plug your device into a power source and click on the Download and Install button.
For macOS users, the 10.14.3 update may automatically be installed.
