"Several vulnerabilities have been discovered in dbus, an asynchronous
inter-process communication system. The Common Vulnerabilities and
Exposures project identifies the following problems :

  - CVE-2014-3477
    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.

  - CVE-2014-3532
    Alban Crequy at Collabora Ltd. discovered a bug in
    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
    sending them a message containing a file descriptor,
    leading to a denial of service.

  - CVE-2014-3533
    Alban Crequy at Collabora Ltd. and Alejandro Martinez
    Suarez discovered that a malicious process could force
    services to be disconnected from the D-Bus system by
    causing dbus-daemon to attempt to forward invalid file
    descriptors to a victim process, leading to a denial of
    service."
