"According to its self-reported version number, the remote installation
of BIND is potentially affected by a denial of service vulnerability,
when configured as a recursive resolver with DNSSEC validation, due to
an error that occurs during the validation of specially crafted zone
data returned in an answer to a recursive query. A remote attacker can
exploit this, by causing a query to be performed against a maliciously
constructed zone, to crash the resolver.
Note that Nessus has not tested for this issue but has instead relied
only on the application's self-reported version number.");
