Red Hat Security Advisory: security problems with ypservOct 28, 1999, 18:18 (3 Talkback[s])
Red Hat, Inc. Security Advisory
Synopsis: security problems with ypserv
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.
