A recently reported bug in Facetime, caused privacy concerns last month as individuals were able to eavesdrop on users. The bug allowed anyone on Group Facetime to hear audio from the user whilst calling them. The glitch permitted this to happen before the user was able to answer or reject the call. Apple temporarily disabled the feature upon discovery. Users were further advised to disable Facetime as an extra measure until Apple fixed the bugs.
Apple has now released the following patches to remediate the bugs found:
- Shortcuts 2.1.3 for iOS
- MacOS Mojave 10.14.3 Supplemental Update
- iOS 12.1.4
Apple released security content for shortcuts 2.1.2 for iOS to patch vulnerability CVE-2019-7289 and CVE-2019-7290. It improved path validation to stop local users viewing sensitive user information. The second shortcut dealt with the sandboxing issue by adding more sandbox restrictions.
MacOS Mojave 10.14.3 Supplemental Update

Improving state management patched CVE-2019-6223 vulnerability. Live photos in Facetime received patching following a security audit carried out by Apple. Vulnerability CVE-2019-7286 is also patched with improved input validation, mitigating abuse in elevated privilege access.
