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.
With Rapid7 live dashboards, I have a clear view of all the assets on my network, which ones can be exploited, and what I need to do in order to reduce the risk in my environment in real-time. No other tool gives us that kind of value and insight.
