A potentially dangerous permissions bug in TeamViewer grants unauthorised access to either the client or the server. Windows, Mac, and LinuxOS are all apparently affected by this bug. Patch may take up to a week to fully roll out, and patches may take three to seven days to be applied. The fix addresses an issue where one user can gain control of anothers PC without permission. It’s definitely worth updating, as there are shenanigans to be had whether acting as client or server.”]
