  script_tag(name:"insight", value:"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) are additional protocol options that add
authentication and integrity to the DNS protocols.

For a recursive DNS server, a remote attacker sending enough recursive
queries for the replies to arrive after all the interested clients
have left the recursion queue will trigger an INSIST failure in the
named(8) daemon.  Also for a recursive DNS server, an assertion
failure can occur when processing a query whose reply will contain
more than one SIG(covered) RRset.

For an authoritative DNS server serving a RFC 2535 DNSSEC zone which
is queried for the SIG records where there are multiple SIG(covered)
RRsets (e.g. a zone apex), named(8) will trigger an assertion failure
when it tries to construct the response.");
