CVE Names:	CVE-2009-4022

CVE-2009-4022 bind: cache poisoning using not validated DNSSEC responses

Michael Sinatra discovered that BIND was incorrectly caching responses
without performing proper DNSSEC validation, when those responses were
received during the resolution of a recursive client query that
requested DNSSEC records but indicated that checking should be disabled.
A remote attacker could use this flaw to bypass the DNSSEC validation
check and perform a cache poisoning attack if the target BIND server was
receiving such client queries. (CVE-2009-4022)

After installing the update, the BIND daemon (named) will be restarted
automatically.
