Red Hat, Inc. Security Advisory

---------------------------------------------------------------------
1. Topic:
The ypserv package, which contains the ypserv NIS server
and the yppasswdd password-change server, has been discovered
to have security holes.
2. Problem description:
With ypserv, local administrators in the NIS domain could
possibly inject password tables. In rpc.yppasswdd, users
could change GECOS and login shells of other users, and
there is a buffer overflow in the md5 hash generation.
It is recommended that all users of the ypserv package upgrade
to the new packages.
