3. Description:

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.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/kb/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):
