I. Background
BIND 9 is an implementation of the Domain Name System (DNS) protocols.
The named(8) daemon is an Internet Domain Name Server.
DNS Security Extensions (DNSSEC) provides data integrity, origin
authentication and authenticated denial of existence to resolvers.
So, a system where "cat /etc/namedb/named.conf |grep -i dnssec" returns
nothing should not be vulnerable.
Could you confirm this?
bye & Thanks
av.
