Some vulnerabilities were discovered and corrected in bind: The original fix for CVE-2009-4022 was found to be incomplete. BIND was incorrectly caching certain responses without performing proper DNSSEC validation. CNAME and DNAME records could be cached, without proper DNSSEC validation, when received from processing recursive client queries 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 . There was an error in the DNSSEC NSEC/NSEC3 validation code that could cause bogus NXDOMAIN responses to be cached as if they had validated correctly, so that future queries to the resolver would return the bogus NXDOMAIN with the AD flag set . Packages for 2008.0 are provided for Corporate Desktop 2008.0 customers. Additionally BIND has been upgraded to the latest patch release version.
