Several vulnerabilities have been discovered in dbus, an asynchronous
inter-process communication system. The Common Vulnerabilities and
Exposures project identifies the following problems :
Alban Crequy at Collabora Ltd. discovered that
dbus-daemon sends an AccessDenied error to the service
instead of a client when the client is prohibited from
accessing the service. A local attacker could use this
flaw to cause a bus-activated service that is not
currently running to attempt to start, and fail, denying
other users access to this service.

dbus-daemon's support for file descriptor passing. A
malicious process could force system services or user
applications to be disconnected from the D-Bus system by
