"Updated X.org packages that correct a flaw in the way the X.Org X11
xfs font server starts 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.

X.org is an open source implementation of the X Window System. It
provides the basic low-level functionality that full-fledged graphical
user interfaces are designed upon.

A temporary file flaw was found in the way the X.Org X11 xfs font
server startup script executes. A local user could modify the
permissions of the file of their choosing, possibly elevating their
local privileges (CVE-2007-3103).

Users of X.org should upgrade to these updated packages, which contain
a backported patch and are not vulnerable to these issues."
