Package : dbus
CVE ID : CVE-2014-3477 CVE-2014-3532 CVE-2014-3533
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.
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.
