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. ISC BIND antes de su versión v9.7.2-P2, cuando la validación DNSSEC está habilitada, no controla correctamente ciertas firmas incorrectas si existen múltiples puntos confianza para una sola zona, lo que permite a atacantes remotos provocar una denegación de servicio (bloqueo del demonio) a través de una consulta DNS. • http://ftp.isc.org/isc/bind9/9.7.2-P2/RELEASE-NOTES-BIND-9.7.2-P2.html http://lists.vmware.com/pipermail/security-announce/2011/000126.html http://support.avaya.com/css/P8/documents/100124923 http://www.debian.org/security/2010/dsa-2130 http://www.mandriva.com/security/advisories?name=MDVSA-2010:253 http://www.redhat.com/support/errata/RHSA-2010-0976.html http://www.securityfocus.com/archive/1/516909/100/0/threaded http://www.securityfocus.com/bid/45385 http:/ • CWE-20: Improper Input Validation •

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. ISC BIND 9.0.x a 9.3.x, 9.4 en versiones anteriores a la 9.4.3-P5, 9.5 en versiones anteriores a la 9.5.2-P2, 9.6 en versiones anteriores a la 9.6.1-P3, y 9.7.0 beta maneja de manera inapropiada los datos de acompañamiento de una respuesta segura sin volver a consultar a la fuente original, lo que permite a atacantes remotos tener un impacto no especificado mediante una respuesta manipulada, también conocido como Bug 20819.
