Scientific Linux Security Update : bind on SL5.x i386/x86_64

Medium Nessus Plugin ID 60920


The remote Scientific Linux host is missing one or more security updates.


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.
