Test ID:1.3.6.1.4.1.25623.1.0.70065
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2011:1132
Summary:NOSUMMARY
Description:Description:
The remote host is missing updates announced in
advisory RHSA-2011:1132.

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.

Solution:
Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
