The exploitation of the flaw was very trivial, a malformed RTP (Real-time Transport Protocol) packet sent to a user, a call request, could have been used to trigger the memory heap overflow and cause the crash of the application.
“This issue can occur when a WhatsApp user accepts a call from a malicious peer. It affects both the Android and iPhone clients.” reads the report published by Silvanovich.
