RHEL 5 : dbus (RHSA-2008:0159)
Medium Nessus Plugin ID 31308
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated 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.
SolutionUpdate the affected dbus, dbus-devel and / or dbus-x11 packages.
