BIND servers can be remotely queried for their version

[wen]

   hi,all:

BIND servers can be remotely queried for their version.this feature could be used by attackers to remotely probe machines for vulnerable versions of BIND to be exploited in later attacks.
now my BIND version is 8.2. how to cancel this fault?

thanks in advance.
