CVE-2014-3477 Information

Description

The dbus-daemon in D-Bus 1.2.x through 1.4.x 1.6.x before 1.6.20 and 1.8.x before 1.8.4 sends an AccessDenied error to the service instead of a client when the client is prohibited from accessing the service which allows local users to cause a denial of service (initialization failure and exit) or possibly conduct a side-channel attack via a D-Bus message to an inactive service.
