CVE-2010-3762: ISC BIND before 9.7.2-P2, when DNSSEC validation is enabled, does not properly handle certain bad signature...

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.

Security readout for executives and security teams

A remote DNS request could crash affected BIND DNS servers when DNSSEC validation is enabled and multiple trust anchors exist for one zone. The impact is service outage, not data theft, but DNS availability can affect authentication, routing, email, and application access. Exposure is most likely on legacy BIND deployments older than 9.7.2-P2 with DNSSEC validation enabled and multiple trust anchors for one zone. Downstream packages were referenced by Linux distribution and VMware advisories, so appliances or service consoles bundling BIND may also matter. Prioritize remediation for internet-facing or business-critical DNS services because a crash can interrupt name resolution. The issue is old, but legacy infrastructure and embedded vendor packages can persist. Lower priority only when BIND is not affected, DNSSEC validation is disabled, or the service is not reachable. Mitigation focus: Upgrade BIND to 9.7.2-P2 or a vendor-fixed package where applicable.; Review Red Hat, Debian, Mandriva, VMware, Avaya, or ISC guidance for packaged fixes.; Inventory DNSSEC-validating resolvers and authoritative DNS infrastructure running legacy BIND..
