Red Hat Security Advisory

Synopsis: Moderate: dbus security update
Advisory ID: RHSA-2010:0018-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0018.html
Issue date: 2010-01-07
CVE Names: CVE-2009-1189
=====================================================================

1. Summary:

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

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

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.

It was discovered that the Red Hat Security Advisory RHSA-2009:0008 did
not correctly fix the denial of service flaw in the system for sending
messages between applications. A local user could use this flaw to send a
message with a malformed signature to the bus, causing the bus (and,
consequently, any process using libdbus to receive messages) to abort.
(CVE-2009-1189)

Note: Users running any application providing services over the system
message bus are advised to test this update carefully before deploying it
in production environments.

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 that all previously-released
errata relevant to your system have been applied.

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