Synopsis:	Important: bind security update
Issue date:	2010-12-13
CVE Names:	CVE-2010-3613 CVE-2010-3614 CVE-2010-3762

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.
