BIND 9.7.1 and 9.7.1-P1, when a recursive validating server has a trust anchor that is configured statically or via DNSSEC Lookaside Validation (DLV), allows remote attackers to cause a denial of service (infinite loop) via a query for an RRSIG record whose answer is not in the cache, which causes BIND to repeatedly send RRSIG queries to the authoritative servers. BIND v9.7.1 y v9.7.1-P1, cuando un servidor de validación recursivo tiene un identificador de confianza que es configurado estáticamente o a través de DNSSEC Lookaside Validation (DLV), permite a atacantse causar una denegación de servicio (bucle infinito) a través de una petición para un registro RRSIG cuya respuesta no está en la caché, lo que causa en BIND el envío repetivamente de peticiones RRSI a los servidores de autorización. • http://lists.fedoraproject.org/pipermail/package-announce/2010-July/044445.html http://lists.opensuse.org/opensuse-security-announce/2010-11/msg00001.html http://secunia.com/advisories/40652 http://secunia.com/advisories/40709 http://www.isc.org/software/bind/advisories/cve-2010-0213 http://www.kb.cert.org/vuls/id/211905 http://www.securityfocus.com/bid/41730 http://www.securitytracker.com/id?1024217 http://www.vupen.com/english/advisories/2010/1884 • CWE-19: Data Processing Errors •

ISC DHCP 4.1 before 4.1.1-P1 and 4.0 before 4.0.2-P1 allows remote attackers to cause a denial of service (server exit) via a zero-length client ID. ISC DHCP v4.1 anterior v4.1.1-P1 y v4.0 anterior v4.0.2-P1 permite a atacantes remotos causar una denegación de servicio (salida servidor) a través de un cliente ID zero-length. • https://www.exploit-db.com/exploits/14185 http://ftp.isc.org/isc/dhcp/dhcp-4.0.2-P1-RELNOTES http://ftp.isc.org/isc/dhcp/dhcp-4.1.1-P1-RELNOTES http://lists.fedoraproject.org/pipermail/package-announce/2010-June/042843.html http://secunia.com/advisories/40116 http://www.exploit-db.com/exploits/14185 http://www.mandriva.com/security/advisories?name=MDVSA-2010:114 http://www.securityfocus.com/bid/40775 http://www.securitytracker.com/id?1024093 https://exchange.xfor • CWE-189: Numeric Errors •

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. NOTA: esta vulnerabilidad existe debido a una regresión durante la solución de CVE-2009-4022. • http://secunia.com/advisories/40086 http://wiki.rpath.com/wiki/Advisories:rPSA-2010-0018 http://www.debian.org/security/2010/dsa-2054 http://www.vupen.com/english/advisories/2010/0622 http://www.vupen.com/english/advisories/2010/1352 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A11753 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A6665 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval •

Unspecified vulnerability in 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, with DNSSEC validation enabled and checking disabled (CD), allows remote attackers to conduct DNS cache poisoning attacks by receiving a recursive client query and sending a response that contains (1) CNAME or (2) DNAME records, which do not have the intended validation before caching, aka Bug 20737. NOTE: this vulnerability exists because of an incomplete fix for CVE-2009-4022.
