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.
