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.

A denial of service flaw was discovered in the system for sending messages
between applications. A local user could send a message with an excessive
number of nested variants to the system-wide message bus, causing the
message bus (and, consequently, any process using libdbus to receive
messages) to abort. (CVE-2010-4352)

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

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