RHEL 5 : dbus (RHSA-2009:0008)

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.

A denial-of-service flaw was discovered in the system for sending
messages between applications. A local user could 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-2008-3834)

All users are advised to upgrade to these updated dbus packages, which
contain backported patch which resolve this issue. For the update to
take effect, all running instances of dbus-daemon and all running
applications using libdbus library must be restarted, or the system
rebooted.
