This is from IBM. I don't know why they do not post to BUGTRAQ directly.

I don't speak for IBM, but I think I know why...

  AIX 4.3:   IY19897  (updated 6/2001)

This is the 'packaging APAR' that rolls all these fixes up so you can
do a one-stop order.  They cut a new roll-up ever 4-5 months.

Due to the way IBM packages things, it includes *EVERY* security fix
that IBM has put into an APAR since AIX 4.3.0 was released.

I just checked the machine in my office - I installed AIX 4.3.0
on November 14, 1997.  That's why there's such a long list - it
goes back that far.

IX72045  CDE LOGIN GIVES INVALID USER NAME MESSAGE BEFORE PW ENTERED

This is a fix for a bug originally reported against AIX 4.2.1.  It's *so*
old that I can't even get accurate date info on when it was released.
Looks around late 97.

I don't think anybody really wants to see *all* 133 bugfixes every
time.  Over and over.  For 4 year old fixes.  I do AIX for a living,
and even *I* yawn at this posting and diff it against the previous
one for any *NEW* ones.

IBM *DOES* post their ERS alerts to Bugtraq (such as the 'diagrpt'
one the other day).  In addition, they have a summary posting that
you can subscribe to that lists the last 7-8 alerts.  Those include
impact, workaround, and fix info - much more helpful..

Diff against the January posting:

*yawn*.  The ERS summaries are much more helpful... Let's encourage those instead.
