Description
A flaw was discovered in ibus in versions before 1.5.22 that allows any unprivileged user to monitor and send method calls to the ibus bus of another user due to a misconfiguration in the DBus server setup. A local attacker may use this flaw to intercept all keystrokes of a victim user who is using the graphical interface, change the input method engine, or modify other input related configurations of the victim user.

Remediation
Red Hat statement
Gnome uses the ibus input framework only when the user explicitly configures it or when some input method sources are in use, like Korean from the ibus-hangul package or Chinese input methods from the ibus-libpinyin. Input methods like en-US are not handled by ibus, thus if the victim user just use them the attacker will not be able to intercept the key strokes of that user.
