Mandriva Linux Security Advisory : bind (MDVSA-2010:253)

This script is Copyright (C) 2010-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

Multiple vulnerabilities were discovered and corrected in bind :

named in ISC BIND 9.6.2 before 9.6.2-P3, 9.6-ESV before 9.6-ESV-R3,
and 9.7.x before 9.7.2-P3 does not properly handle the combination of
signed negative responses and corresponding RRSIG records in the
cache, which allows remote attackers to cause a denial of service
(daemon crash) via a query for cached data (CVE-2010-3613).

named in ISC BIND 9.x before 9.6.2-P3, 9.7.x before 9.7.2-P3, 9.4-ESV
before 9.4-ESV-R4, and 9.6-ESV before 9.6-ESV-R3 does not properly
determine the security status of an NS RRset during a DNSKEY algorithm
rollover, which might allow remote attackers to cause a denial of
service (DNSSEC validation error) by triggering a rollover
(CVE-2010-3614).

ISC BIND before 9.7.2-P2, when DNSSEC validation is enabled, does not
properly handle certain bad signatures if multiple trust anchors exist
for a single zone, which allows remote attackers to cause a denial of
service (daemon crash) via a DNS query (CVE-2010-3762).
