CVE-2016-2775 – bind: Too long query name causes segmentation fault in lwresd

https://notcve.org/view.php?id=CVE-2016-2775

ISC BIND 9.x before 9.9.9-P2, 9.10.x before 9.10.4-P2, and 9.11.x before 9.11.0b2, when lwresd or the named lwres option is enabled, allows remote attackers to cause a denial of service (daemon crash) via a long request that uses the lightweight resolver protocol. ISC BIND 9.x en versiones anteriores a 9.9.9-P2, 9.10.x en versiones anteriores a 9.10.4-P2 y 9.11.x en versiones anteriores a 9.11.0b2, cuando lwresd o la opción nombrada lwres está habilitada, permite a atacantes remotos provocar una denegación de servicio (caída del demonio) a través de una petición larga que utiliza el protocolo ligero de resolución. It was found that the lightweight resolver protocol implementation in BIND could enter an infinite recursion and crash when asked to resolve a query name which, when combined with a search list entry, exceeds the maximum allowable length. A remote attacker could use this flaw to crash lwresd or named when using the "lwres" statement in named.conf. • http://www.securityfocus.com/bid/92037 http://www.securitytracker.com/id/1036360 https://access.redhat.com/errata/RHBA-2017:0651 https://access.redhat.com/errata/RHBA-2017:1767 https://access.redhat.com/errata/RHSA-2017:2533 https://h20566.www2.hpe.com/portal/site/hpsc/public/kb/docDisplay?docId=emr_na-c05321107 https://kb.isc.org/article/AA-01393/74/CVE-2016-2775 https://kb.isc.org/article/AA-01435 https://kb.isc.org/article/AA-01436 https://kb.isc.org&#x • CWE-20: Improper Input Validation •

CVE-2016-6170

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
