Major security holes have been found in the X libraries and xterm, which
allow local users access to the root user. All Red Hat 4.x and 5.x systems
which X-Windows installed should update their systems. Packages for the
SPARC are not yet available. When they are, we will post a separate 
announcement so sparc-list@redhat.com providing full information on those
fixes.

Thanks to the XFree86 group for providing patches for these problems.
