                 SECURITY: new ftp client packages available
                              18 December 1998

===========================================================================

Redhat has released the following revised bulletin concerning a
vulnerability in the ftp client binary available for all supported
releases of Red Hat Linux.

- --------------------------BEGIN INCLUDED TEXT--------------------

- -----BEGIN PGP SIGNED MESSAGE-----

A security vulnerability has been identified in all versions of the ftp
client binary shipped with Red Hat Linux.  An exploit for this vulnerability
would have to rely on getting the user to connect using passive mode to a
server running a ftp daemon under the attacker's control.  As of this release
time there are no known exploits of this security problem.

All users of Red Hat Linux are encouraged to upgrade to the new package
releases immediately.  As always, these packages have been signed with the
Red Hat PGP key.
