K15172 : BIND vulnerability CVE-2010-3762

Security Advisory Description

Description

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)

Impact

If BIND has been manually configured to perform Domain Name System Security Extensions (DNSSEC) validation on nameservers, a malicious remote attacker may cause a disruption of service on those nameservers.
