"Updated dbus packages that fix a security issue are now available for
Red Hat Enterprise Linux 4.

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 both for the systemwide message bus service, and as a
per-user-login-session messaging facility.

Kimmo Hamalainen discovered a flaw in the way D-BUS processes certain
messages. It is possible for a local unprivileged D-BUS process to
disrupt the ability of another D-BUS process to receive messages.
(CVE-2006-6107)

Users of dbus are advised to upgrade to these updated packages, which
contain backported patches to correct this issue."
