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

This script is Copyright (C) 2012 Tenable Network Security, Inc.


Synopsis :

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

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.
