BIND Bugs Let Remote Users Bypass Access Controls and Deny Service
SecurityTracker Alert ID:  1024817
SecurityTracker URL:  http://securitytracker.com/id/1024817
CVE Reference:   CVE-2010-3613, CVE-2010-3614, CVE-2010-3615   (Links to External Site)
Date:  Dec 2 2010
Impact:   Denial of service via network, Host/resource access via network, Modification of system information
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 9.0.x to 9.7.2-P2, 9.4-ESV to 9.4-ESV-R3, 9.6-ESV to 9.6-ESV-R2
Description:   Several vulnerabilities were reported in BIND. A remote user can cause denial of service conditions. A remote user can bypass access controls.

When certain types of signed negative responses are added to the cache, matching RRSIG records already in the cache are not cleared [CVE-2010-3613]. A remote user can subsequently perform a lookup of the cached data can cause named to crash.

When named is acting as a DNSSEC validator, it may incorrectly determine that an NS RRset is insecure when there isn't a matching key for the RRSIG in the DNSKEY RRset when resuming from validating the DNSKEY RRset (such as during a DNSKEY algorithm rollover when two different algorithms are used to sign a zone but only the new set of keys are in the zone DNSKEY RRset) [CVE-2010-3614].

When named is running as an authoritative server for a zone and the allow-query statement is not set in the zone statement, the system defaults to allowing the query [CVE-2010-3615]. A remote user can send a query for that zone data to bypass the access controls.

Impact:   A remote user can cause denial of service conditions.

A remote user can bypass access controls.

Solution:   The vendor has issued a fix (9.7.2-P3).
