WhatsApp fixes a security issue in video calls

Natalie Silvanovich, security researcher at Google Project Zero, found a vulnerability in August 2018, reported later to WhatsApp, that could compromise an account by simply responding to a video call.

The vulnerability is memory heap overflow type and is found in the WhatsApp RTP implementation, so the bug affects both Android and iOS versions, but not WhatsApp Web, as it uses WebRTC for making video calls.

Ann Yeh, WhatsApp spokeswoman, said they regularly collaborate with security researchers around the world to ensure the application remains secure and reliable. The company released an update that resolves the bug on September 28, 2018 for the Android version and October 3, 2018 for the iOS version.
