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. For the stable distribution (wheezy), these problems have been fixed in version 1.6.8-1+deb7u3. For the unstable distribution (sid), these problems have been fixed in version 1.8.6-1. We recommend that you upgrade your dbus packages.
