Synopsis:    Moderate: dbus security update
Issue Date:  2011-08-09
CVE Numbers: CVE-2011-2200


D-Bus is a system for sending messages between applications. It is used 
for the system-wide message bus service and as a per-user-login-session
messaging facility.

A denial of service flaw was found in the way the D-Bus library handled
endianness conversion when receiving messages. A local user could use 
this flaw to send a specially-crafted message to dbus-daemon or to a 
service using the bus, such as Avahi or NetworkManager, possibly causing 
the daemon to exit or the service to disconnect from the bus. 
(CVE-2011-2200)

All users are advised to upgrade to these updated packages, which 
contain a backported patch to correct this issue. For the update to take 
effect, all running instances of dbus-daemon and all running 
applications using the libdbus library must be restarted, or the system 
rebooted.
