- --- Issue Specifics ---
- -----------------------
SGI acknowledges awareness of the "denial-of-service attacks in
TCP/IP stacks" vulnerability reported by BindView on
http://razor.bindview.com/publish/advisories/adv_NAPTHA.html
and by CERT CA-2000-21 on http://www.cert.org/advisories/CA-2000-21.html
and is continuing to explore ways to defend against and minimize such attacks
within IRIX. 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 fixes are available for all vulnerable and supported 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.
