RHEL 5 : dbus (RHSA-2010:0018)

This script is Copyright (C) 2010-2014 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

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.

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.
