The package guake before 3.8.5 are vulnerable to Exposed Dangerous Method
or Function due to the exposure of execute_command and
execute_command_by_uuid methods via the d-bus interface, which makes it
possible for a malicious user to run an arbitrary command via the d-bus
method. Note: Exploitation requires the user to have installed another
malicious program that will be able to send dbus signals or run terminal
commands.
