ISC BIND through 9.9.9-P1, 9.10.x through 9.10.4-P1, and 9.11.x through 9.11.0b1 allows primary DNS servers to cause a denial of service (secondary DNS server crash) via a large AXFR response, and possibly allows IXFR servers to cause a denial of service (IXFR client crash) via a large IXFR response and allows remote authenticated users to cause a denial of service (primary DNS server crash) via a large UPDATE message. ISC BIND hasta la versión 9.9.9-P1, 9.10.x hasta la versión 9.10.4-P1 y 9.11.x hasta la versión 9.11.0b1 permite a servidores DNS primarios provocar una denegación de servicio (caída de servidor DNS secundario) a través de una respuesta AXFR grande, y posiblemente permite a servidores IXFR provocar una denegación de servicio (caída de cliente IXFR) a través de una respuesta IXFR grande y permite a usuarios remotos autenticados provocar una denegación de servicio (caída de servidor DNS primario) a través de un mensaje UPDATE grande. • http://www.openwall.com/lists/oss-security/2016/07/06/3 http://www.securityfocus.com/bid/91611 http://www.securitytracker.com/id/1036241 https://bugzilla.redhat.com/show_bug.cgi?id=1353563 https://github.com/sischkg/xfer-limit/blob/master/README.md https://kb.isc.org/article/AA-01390 https://kb.isc.org/article/AA-01390/169/CVE-2016-6170 https://lists.dns-oarc.net/pipermail/dns-operations/2016-July/015058.html https://lists.dns-oarc.net/pipermail/dns-operations&# • CWE-20: Improper Input Validation •

named in ISC BIND 9.x before 9.9.8-P4 and 9.10.x before 9.10.3-P4 does not properly handle DNAME records when parsing fetch reply messages, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a malformed packet to the rndc (aka control channel) interface, related to alist.c and sexpr.c. named en ISC BIND 9.x en versiones anteriores a 9.9.8-P4 y 9.10.x en versiones anteriores a 9.10.3-P4 no maneja adecuadamente los archivos DNAME cuando analiza gramaticalmente la recuperación de mensajes contestados, lo que permite a atacantes remotos provocar una denegación de servicio (fallo de aserción y salida de demonio) a través de un paquete mal formado en la interfaz rndc (también conocido como canal de control), relacionado con alist.c y sexpr.c. A denial of service flaw was found in the way BIND processed certain control channel input. A remote attacker able to send a malformed packet to the control channel could use this flaw to cause named to crash. • http://lists.fedoraproject.org/pipermail/package-announce/2016-April/181036.html http://lists.fedoraproject.org/pipermail/package-announce/2016-April/181037.html http://lists.fedoraproject.org/pipermail/package-announce/2016-March/178831.html http://lists.fedoraproject.org/pipermail/package-announce/2016-March/178880.html http://lists.fedoraproject.org/pipermail/package-announce/2016-March/179904.html http://lists.fedoraproject.org/pipermail/package-announce/2016-March/179911.html http://lists.opensuse.org/opensuse- • CWE-617: Reachable Assertion •

named in ISC BIND 9.x before 9.9.8-P4 and 9.10.x before 9.10.3-P4 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a crafted signature record for a DNAME record, related to db.c and resolver.c. named en ISC BIND 9.x en versiones anteriores a 9.9.8-P4 y 9.10.x en versiones anteriores a 9.10.3-P4 permite a atacantes remotos provocar una denegación de servicio (fallo de aserción y salida de demonio) a través de un registro de firma manipulado para un registro DNAME, relacionada con db.c y resolver.c. A denial of service flaw was found in the way BIND parsed signature records for DNAME records. By sending a specially crafted query, a remote attacker could use this flaw to cause named to crash. • http://lists.fedoraproject.org/pipermail/package-announce/2016-April/181036.html http://lists.fedoraproject.org/pipermail/package-announce/2016-April/181037.html http://lists.fedoraproject.org/pipermail/package-announce/2016-March/178831.html http://lists.fedoraproject.org/pipermail/package-announce/2016-March/178880.html http://lists.fedoraproject.org/pipermail/package-announce/2016-March/179904.html http://lists.fedoraproject.org/pipermail/package-announce/2016-March/179911.html http://lists.opensuse.org/opensuse- • CWE-617: Reachable Assertion •

buffer.c in named in ISC BIND 9.10.x before 9.10.3-P3, when debug logging is enabled, allows remote attackers to cause a denial of service (REQUIRE assertion failure and daemon exit, or daemon crash) or possibly have unspecified other impact via (1) OPT data or (2) an ECS option. buffer.c en named en ISC BIND 9.10.x en versiones anteriores a 9.10.3-P3, cuando inicio de sesión depurado está habilitado, permite a atacantes remotos provocar una denegación de servicio (error de aserción REQUIRE y salida del demonio, o caída del demonio) o posiblemente tener otro impacto no especificado a través de (1) datos OPT o (2) una opción ECS. • http://lists.fedoraproject.org/pipermail/package-announce/2016-February/176564.html http://lists.fedoraproject.org/pipermail/package-announce/2016-January/175977.html http://www.oracle.com/technetwork/topics/security/bulletinoct2016-3090566.html http://www.securityfocus.com/bid/81314 http://www.securitytracker.com/id/1034740 https://kb.isc.org/article/AA-01336 https://kb.isc.org/article/AA-01380 https://security.gentoo.org/glsa/201610-07 • CWE-20: Improper Input Validation •

apl_42.c in ISC BIND 9.x before 9.9.8-P3, 9.9.x, and 9.10.x before 9.10.3-P3 allows remote authenticated users to cause a denial of service (INSIST assertion failure and daemon exit) via a malformed Address Prefix List (APL) record. apl_42.c en ISC BIND 9.x en versiones anteriores a 9.9.8-P3, 9.9.x y 9.10.x en versiones anteriores a 9.10.3-P3 permite a usuarios remotos autenticados provocar una denegación de servicio (fallo de la afirmación INSIST y salida de demonio) a través de un registro Address Prefix List (APL) mal formado. A denial of service flaw was found in the way BIND processed certain malformed Address Prefix List (APL) records.
