RHEL 4 : dbus (RHSA-2005:102)
Low Nessus Plugin ID 18441
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated dbus packages that fix a security issue are now available for Red Hat Enterprise Linux 4.
This update has been rated as having low 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.
Dan Reed discovered that a user can send and listen to messages on another user's per-user session bus if they know the address of the socket. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-0201 to this issue. In Red Hat Enterprise Linux 4, the per-user session bus is only used for printing notifications, therefore this issue would only allow a local user to examine or send additional print notification messages.
Users of dbus are advised to upgrade to these updated packages, which contain backported patches to correct this issue.
SolutionUpdate the affected packages.
