Mandriva Linux Security Advisory : bind (MDVSA-2010:021)

High Nessus Plugin ID 44102


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


Some vulnerabilities were discovered and corrected in bind :

The original fix for CVE-2009-4022 was found to be incomplete. BIND was incorrectly caching certain responses without performing proper DNSSEC validation. CNAME and DNAME records could be cached, without proper DNSSEC validation, when received from processing recursive client queries that requested DNSSEC records but indicated that checking should be disabled. A remote attacker could use this flaw to bypass the DNSSEC validation check and perform a cache poisoning attack if the target BIND server was receiving such client queries (CVE-2010-0290).

There was an error in the DNSSEC NSEC/NSEC3 validation code that could cause bogus NXDOMAIN responses (that is, NXDOMAIN responses for records proven by NSEC or NSEC3 to exist) to be cached as if they had validated correctly, so that future queries to the resolver would return the bogus NXDOMAIN with the AD flag set (CVE-2010-0097).

ISC BIND 9.0.x through 9.3.x, 9.4 before 9.4.3-P5, 9.5 before 9.5.2-P2, 9.6 before 9.6.1-P3, and 9.7.0 beta handles out-of-bailiwick data accompanying a secure response without re-fetching from the original source, which allows remote attackers to have an unspecified impact via a crafted response, aka Bug 20819. NOTE: this vulnerability exists because of a regression during the fix for CVE-2009-4022 (CVE-2010-0382).

Packages for 2008.0 are provided for Corporate Desktop 2008.0 customers.

Additionally BIND has been upgraded to the latest patch release version.


Update the affected packages.
