Win : ISS Security Advisory: Buffer Overflow in NetscapeEnterprise and FastTrack Web Servers

This is all kind of ominous, and we have a bunch of Irix machines
running the netscape web server, I think - many unnecessarily.  Sadly, I
don't think we can count on netscape to be forthcoming about this.

Could you please go to the machines running the netscape web server and
turn it off on the ones that don't actually need it?

I'm leaving a copy of the web-80 entries from ~oacstats/composite in
/tmp on nsc-1.oac, to help you identify which machines are running a
netscape server.

  We tested the vulnerability against the current releases of Enterprise
  and Fasttrack.  Earlier versions may be vulnerable, but they were not
  tested against.

  No, our advisory effects only NT, Solaris was tested against and found
  not vulnerable.  AIX and other platforms were not tested against and
  these platforms potentially could be vulnerable.

  Netscape decided to combine the GET overflow patch in with an SSL
  problem.  This vulnerability affects the entire server.  Netscapes
  handles their patch bundling, we have no involvment with that.

  Not that we know of, If previous versions are found to be vulnerable
  Netscape should be contacted and will issue a patch at that time.
