bind -- Multiple Denial of Service vulnerabilities

Problem Description:
A type * (ANY) query response containing multiple RRsets can
trigger an assertion failure.
Certain recursive queries can cause the nameserver to crash
by using memory which has already been freed.
Impact:
A remote attacker sending a type * (ANY) query to an
authoritative DNS server for a DNSSEC signed zone can cause
the named(8) daemon to exit, resulting in a Denial of
Service.
A remote attacker sending recursive queries can cause the
nameserver to crash, resulting in a Denial of Service.
Workaround:
There is no workaround available, but systems which are not
authoritative servers for DNSSEC signed zones are not
affected by the first issue; and systems which do not permit
untrusted users to perform recursive DNS resolution are not
affected by the second issue. Note that the default
configuration for named(8) in FreeBSD allows local access
only (which on many systems is equivalent to refusing access
to untrusted users).
