dbus security update.
Security Advisory: Low
Updated 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 CAN-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.
Before applying this update, make sure that all previously-released
