New FaceTime Bug Lets Callers Hear and See You Without You Picking Up (Jan 29, 2019)

An unpatched bug in Apple’s FaceTime application was discovered that allows a person initiating a call to hear or see the recipient before they accept the call. This could allow a user to call any iPhone number via FaceTime and eavesdrop, even when the call is not actively answered. The bug works on the latest iOS version: iOS 12.1.2, as well as macOS Mojave.

Recommendation: While Apple is developing a patch for this bug, they suggest that users temporarily disable FaceTime video calling on phones, tablets, and computers. Users should remain vigilant of a patch as soon as it is released and apply it immediately. Apple has disabled the feature on the server side, which will prevent exploitation of this flaw in the meantime.
