Simon McVittie reported a flaw in ibus, the Intelligent Input Bus. Due to a misconfiguration during the setup of the DBus, any unprivileged user could monitor and send method calls to the ibus bus of another user, if able to discover the UNIX socket used by another user connected on a graphical environment.
