«a WhatsApp exploit that could inject malware onto targeted 
phones—and steal data from them—simply by calling them. The 
targets didn't need to pick up to be infected, and the calls 
often left no trace on the phone's log. ...

«While WhatsApp bases its end-to-end encryption on the Signal 
Protocol, its VoIP calling functionally likely also includes 
other proprietary code as well. Signal says that its service is 
not vulnerable to this calling attack.

«According to Facebook's security advisory, the WhatsApp 
vulnerability stemmed from an extremely common type of bug known 
as a buffer overflow.»
