Scientific Linux Security Update : dbus on SL5.x, SL6.x i386/x86_64

This script is Copyright (C) 2012 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

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.
