(BIND: Denial of Service)

    Queries for SIG records will cause an assertion error if more than one
    SIG RRset is returned. Additionally, an INSIST failure can be triggered
    by sending multiple recursive queries if the response to the query
    arrives after all the clients looking for the response have left the
    recursion queue.
  
Impact :

    An attacker having access to a recursive server can crash the server by
    querying the SIG records where there are multiple SIG RRsets, or by
    sending many recursive queries in a short time. The exposure can be
    lowered by restricting the clients that can ask for recursion. An
    attacker can also crash an authoritative server serving a DNSSEC zone
    in which there are multiple SIG RRsets.
  
Workaround :

    There are no known workarounds at this time."

"Problem Description 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. Impact An attacker who can
perform recursive lookups on a DNS server and is able to send a
sufficiently large number of recursive queries, or is able to get the
DNS server to return more than one SIG(covered) RRsets can stop the
functionality of the DNS service.

An attacker querying an authoritative DNS server serving a RFC 2535
DNSSEC zone may be able to crash the DNS server. Workaround A possible
workaround is to only allow trusted clients to perform recursive
queries."
