SGI acknowledges the BIND name server vulnerability reported by Vagner
Sacramento in CERT VU# 457875 (
http://www.kb.cert.org/vuls/id/457875 and
http://www.rnp.br/cais/alertas/2002/cais-ALR-19112002a.html) and is
currently investigating.  No further information is available at this time.

For the protection of all our customers, SGI does not disclose, discuss
or confirm vulnerabilities until a full investigation has occurred and
any necessary patch(es) or release streams are available for all vulnerable
and supported Linux and IRIX operating systems.

Until SGI has more definitive information to provide, customers are
encouraged to assume all security vulnerabilities as exploitable and take
appropriate steps according to local site security policies and requirements.

As further information becomes available, additional advisories will be
issued via the normal SGI security information distribution methods
including the wiretap mailing list.
