In reviewing:
http://www.isc.org/products/BIND/bind-security.html and
http://bvlive01.iss.net/issEn/delivery/xforce/alertdetail.jsp?oid=21469
I think I understand what's happening with the OPT bug, but I want to be
sure. This bug affects a resolving name server when a client sends a query
for something that generates an NXDOMAIN response (plus other nastiness in
the OPT section), correct?
The thing I want to clarify is whether or not this bug can be triggered in
a name server that is authoritative only, and whether or not "fetch-glue
yes" will follow the same resolver path that triggers the bug.
Thanks,
Doug
