I did quite a bit of searching on the Web. It seems that
configuring BIND securely and correctly is difficult.
All I can offer is a long discussion by Sean Boran here:
Section 4 "Setting Jail Permissions" and
following that may be useful. There is also a list of
refernces at the end of the paper.
P.S.: The paper refers to Solaris OS. Of course
I don't know if it's a Fedora 10 problem, a
configuration or permissions problem, or
something else, or a mixture. But it looks
like a reference with good advice for DNS
hope this helps,
