Serious security problem with yppasswdd

Does anyone have a Sun Bug Report ID number for this? It's easier to refer
to an existing bug report than to try and describe to Software Support
details of a bug about which we have no details.

[[ Sure.  We have the tape now.  It has new 4.0 executables (for 010, 020,
and sparc) for in.ftpd, sendmail, sendmail.mx, ypbind, rpc.yppasswdd, and
portmap.  There are also 3.5 versions for ypbind and rpc.yppasswdd.  These
are fixes for the following Bug IDs: 1015127, 1015111, 1016711, 1015128,
1016786, 1010710.  But I have it on reasonably good authority (not from
within Sun) that the yppasswdd fix is still not sufficient.  Those
concerned should seriously consider joining the mailing list "Sun-Nets".
Mail requests to "Sun-Nets-request at brillig.umd.edu".  This is being
discussed fairly regularly there.  --wnl ]]
