(RHSA-2007:0520) Moderate: xorg-x11-xfs security update

The X.Org X11 xfs font server provides a standard mechanism for an X server
to communicate with a font renderer.

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 a
file of their choosing, possibly elevating their local privileges.
(CVE-2007-3103)

Users of the X.org X11 xfs font server should upgrade to these updated
packages, which contain a backported patch and are not vulnerable to this
issue.
