RedHat: Moderate: dbus security update
Summary
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.
Summary
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
