Default Bug: A single WhatsApp message can wipe out your group chats

Security researchers from Check Point found a serious security flaw in the
iOS and Android WhatsApp apps (which was updated recently to fix this bug).

"The defect enables a bad actor to deliver a destructive group chat message
that produces a swift and complete crash of the entire application for all
members of the group chat. The crash is so severe that users are forced to
uninstall and reinstall the application, in order to gain proper use of

Furthermore, the user would be unable to return to the group chat, which
would lead to the loss of all group chat history, indefinitely. The group
chat would then not be able to be restored after the crash occurs and would
need to be deleted in order to stop the crash-loop.

Carrying out the attack would be relatively simple. An attacker would use a
web browser debugging tool to edit a message to any group chat. That
message would cause the app to crash for all members, and it would continue
to crash each time anyone tried to open it.

Because the only way to recover would be to delete the app and all its
data, then reinstall from scratch, all chat history in the group would be
lost for all members.

Check Point followed the usual responsible disclosure process, advising
WhatsApp of the details, and waiting for the company to issue an update to
fix it before going public.

That has now been done, and you can protect yourself and your groups from
this by ensuring you update WhatsApp to the latest version. "

Informing users of new bugs so that they can update their apps accordingly.
