a specially crafted dynamic DNS update. This vulnerability affects all
BIND servers which serve at least one DNS zone authoritatively, as a
master, even if dynamic updates are not enabled. The default Debian
configuration for resolvers includes several authoritative zones, too,
so resolvers are also affected by this issue unless these zones have
been removed."
