The remote host is missing an update to bind
announced via advisory MDVSA-2010:253.
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).
