I'm confused <g> ... the HP alert indicates that problem "HPSBUX0011-130"
is both a "DoS at boot-time" problem, and a remote root compromise - [see
"DAMAGE" and "Background" below].

So which is it ? Maybe it's both, but if it's just boot-time DoS I can
live with that for a spell.

The man page says :
      auto_parms is a system initialization script whose primary
      responsibility lies in handling first time boot configuration and
      ongoing management of the DHCP lease(s).

The script is 1700 lines long, so I don't want to have to try to analyse it
myself. Since it deals with DHCP address requesting, I suppose it may be
vulnerable to something like the recent ISC DHCP client vulnerability (if
there exists a malicious DHCP server somewhere), but HP don't give any
clues.

Does anyone understand this better than me ?
[It matters a bit to me - many systems to fix - as to quite how much panic I
allow myself ...]

I'd log a call with HP to ask, but I've not had a useful result from that
course in the past.

Thanks,
