"From Red Hat Security Advisory 2011:1132 :

Updated dbus packages that fix one security issue are now available
for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.

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."
