Actually, that is a different check than the one I originally posted.
You are correct, BindVrs is a low. BindHostnameDisclosure is a BIND9
check that is a Medium. See below...
M BindHostnameDisclosure: BIND hostname disclosure
BIND (the Berkeley Internet Name Daemon) is the Domain Name Service for
Unix systems. BIND versions 9.0 and later could allow
a remote attacker to obtain sensitive information. By sending
specially-crafted DNS query for the record AUTHORS.BIND a remote
attacker may learn the BIND software version and the hostname of the DNS
server. This information could be helpful in launching
No remedy available as of January 2005.
L bindvrs: BIND servers can be remotely queried for their version
BIND (Berkeley Internet Name Domain) servers support the ability to be
remotely queried for their version numbers. An attacker
could use this feature to query computers for vulnerable versions of
BIND. This information could be useful to an attacker in
performing an attack.
Disable the BIND version query feature. Refer to the BIND documentation
for information on this procedure.
