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.

Notes

Author	Note
alexmurray	The ibus D-Bus socket address contains a long random guid making discovery of this address by another user unlikely.
mdeslaur	this was reverted in 4134-2 because of a regression, see LP bug
