1. Topic:

The XEmacs package as shipped with Red Hat Linux 7 has a security problem
with gnuserv and gnuclient.

2. Relevant releases/architectures:

Red Hat Linux 7.0 - alpha, i386

3. Problem description:

The XEmacs package as shipped with Red Hat Linux 7 has a security problem
with gnuserv and gnuclient, due to a buffer overflow and weak security.

This update also fixes other minor problems in XEmacs and adds MULE
support.

4. Solution:

To update all RPMs for your particular architecture, run:

rpm -Fvh 

where  is a list of the RPMs you wish to upgrade.  Only those
RPMs which are currently installed will be updated.  Those RPMs which are
not installed but included in the list will not be updated.  Note that you
can also use wildcards (*.rpm) if your current directory *only* contains
the desired RPMs.

Please note that this update is also available via Red Hat Network.  Many
people find this an easier way to apply updates.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
