https://notcve.org/view.php?id=CVE-2016-6170

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 •

CVE-2016-1285 – bind: malformed packet sent to rndc can trigger assertion failure

https://notcve.org/view.php?id=CVE-2016-1285

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 •

CVE-2016-1286 – bind: malformed signature records for DNAME records can trigger assertion failure

https://notcve.org/view.php?id=CVE-2016-1286

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 •
