Description

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.
