"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. The attacker can take advantage
of this flaw to intercept keystrokes of the victim user or modify
input related configurations through DBus method calls.");
