Description

It was discovered that named did not invalidate previously cached RRSIG records when adding an NCACHE record for the same entry to the cache. A remote attacker allowed to send recursive DNS queries to named could use this flaw to crash named. (CVE-2010-3613)

A flaw was found in the DNSSEC validation code in named. If named had multiple trust anchors configured for a zone, a response to a request for a record in that zone with a bad signature could cause named to crash. (CVE-2010-3762)

It was discovered that, in certain cases, named did not properly perform DNSSEC validation of an NS RRset for zones in the middle of a DNSKEY algorithm rollover. This flaw could cause the validator to incorrectly determine that the zone is insecure and not protected by DNSSEC. (CVE-2010-3614)

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