Facebook has patched a bug in its widely installed Messenger app for Android that could have allowed a remote attacker to call unsuspecting targets and listen to them before even they picked up the audio call.
The flaw was discovered and reported to Facebook by Natalie Silvanovich of Google’s Project Zero bug-hunting team last month on October 6 with a 90-day deadline, and impacts version 284.0.0.16.119 (and before) of Facebook Messenger for Android.
