Details

Updated dbus packages that fix an issue with circumventing the security
policy are now available.

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 system-wide message bus service, and as a
per-user-login-session messaging facility.

Havoc Pennington discovered a flaw in the way the dbus-daemon applies its
security policy. A user with the ability to connect to the dbus-daemon may
be able to execute certain method calls they should normally not have
permission to access. (CVE-2008-0595)

Red Hat does not ship any applications in Red Hat Enterprise Linux 5 that
would allow a user to leverage this flaw to elevate their privileges.

This flaw does not affect the version of D-Bus shipped in Red Hat
Enterprise Linux 4.

All users are advised to upgrade to these updated dbus packages, which
contain a backported patch and are not vulnerable to this issue.

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
