font server starts are now available for CentOS Linux 4.
This update has been rated as having moderate security impact by the Red

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