CVSS: 6.5EPSS: 0%CPEs: 2EXPL: 0CVE-2018-5741 – Update policies krb5-subdomain and ms-subdomain do not enforce controls promised in their documentation
https://notcve.org/view.php?id=CVE-2018-5741
To provide fine-grained controls over the ability to use Dynamic DNS (DDNS) to update records in a zone, BIND 9 provides a feature called update-policy. Various rules can be configured to limit the types of updates that can be performed by a client, depending on the key used when sending the update request. Unfortunately, some rule types were not initially documented, and when documentation for them was added to the Administrator Reference Manual (ARM) in change #3112, the language that was added to the ARM at that time incorrectly described the behavior of two rule types, krb5-subdomain and ms-subdomain. This incorrect documentation could mislead operators into believing that policies they had configured were more restrictive than they actually were. This affects BIND versions prior to BIND 9.11.5 and BIND 9.12.3. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00044.html http://www.securityfocus.com/bid/105379 http://www.securitytracker.com/id/1041674 https://access.redhat.com/errata/RHSA-2019:2057 https://kb.isc.org/docs/cve-2018-5741 https://security.gentoo.org/glsa/201903-13 https://security.netapp.com/advisory/ntap-20190830-0001 https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US&doc • CWE-284: Improper Access Control CWE-863: Incorrect Authorization •
CVSS: 7.5EPSS: 94%CPEs: 26EXPL: 0CVE-2018-5740 – A flaw in the "deny-answer-aliases" feature can cause an assertion failure in named
https://notcve.org/view.php?id=CVE-2018-5740
"deny-answer-aliases" is a little-used feature intended to help recursive server operators protect end users against DNS rebinding attacks, a potential method of circumventing the security model used by client browsers. However, a defect in this feature makes it easy, when the feature is in use, to experience an assertion failure in name.c. Affects BIND 9.7.0->9.8.8, 9.9.0->9.9.13, 9.10.0->9.10.8, 9.11.0->9.11.4, 9.12.0->9.12.2, 9.13.0->9.13.2. "deny-answer-aliases" es una característica poco utilizada que pretende ayudar a los operadores recursivos del servidor a proteger a los usuarios finales contra ataques de reenlace DNS, un método para poder eludir el modelo de seguridad empleado por los navegadores del cliente. Sin embargo, un defecto en esta característica hace que sea sencillo experimentar un fallo de aserción en name.c. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00027.html http://www.securityfocus.com/bid/105055 http://www.securitytracker.com/id/1041436 https://access.redhat.com/errata/RHSA-2018:2570 https://access.redhat.com/errata/RHSA-2018:2571 https://kb.isc.org/docs/aa-01639 https://lists.debian.org/debian-lts-announce/2018/08/msg00033.html https://lists.debian.org/debian-lts-announce/2021/11&#x • CWE-617: Reachable Assertion •
CVSS: 7.5EPSS: 5%CPEs: 72EXPL: 0CVE-2017-3145 – Improper fetch cleanup sequencing in the resolver can cause named to crash
https://notcve.org/view.php?id=CVE-2017-3145
BIND was improperly sequencing cleanup operations on upstream recursion fetch contexts, leading in some cases to a use-after-free error that can trigger an assertion failure and crash in named. Affects BIND 9.0.0 to 9.8.x, 9.9.0 to 9.9.11, 9.10.0 to 9.10.6, 9.11.0 to 9.11.2, 9.9.3-S1 to 9.9.11-S1, 9.10.5-S1 to 9.10.6-S1, 9.12.0a1 to 9.12.0rc1. BIND secuenciaba incorrectamente las operaciones de limpieza en contextos fetch de recursión ascendente, lo que conduce en algunos casos a un error de uso de memoria previamente liberada que puede desencadenar un fallo de aserción y un cierre inesperado en named. Afecta a BIND desde la versión 9.0.0 hasta la versión 9.8.x, desde la versión 9.9.0 hasta la versión 9.9.11, desde la versión 9.10.0 hasta la versión 9.10.6, desde la versión 9.11.0 hasta la versión 9.11.2, desde la versión 9.9.3-S1 hasta la versión 09.9.11-S1, desde la versión 9.10.5-S1 hasta la versión 9.10.6-S1 y desde la 9.12.0a1 hasta la 9.12.0rc1. A use-after-free flaw leading to denial of service was found in the way BIND internally handled cleanup operations on upstream recursion fetch contexts. • http://www.securityfocus.com/bid/102716 http://www.securitytracker.com/id/1040195 https://access.redhat.com/errata/RHSA-2018:0101 https://access.redhat.com/errata/RHSA-2018:0102 https://access.redhat.com/errata/RHSA-2018:0487 https://access.redhat.com/errata/RHSA-2018:0488 https://kb.isc.org/docs/aa-01542 https://lists.debian.org/debian-lts-announce/2018/01/msg00029.html https://security.netapp.com/advisory/ntap-20180117-0003 https://supportportal.juniper.net/s/article/ • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2017-3142
An attacker who is able to send and receive messages to an authoritative DNS server and who has knowledge of a valid TSIG key name may be able to circumvent TSIG authentication of AXFR requests via a carefully constructed request packet. A server that relies solely on TSIG keys for protection with no other ACL protection could be manipulated into: providing an AXFR of a zone to an unauthorized recipient or accepting bogus NOTIFY packets. Affects BIND 9.4.0->9.8.8, 9.9.0->9.9.10-P1, 9.10.0->9.10.5-P1, 9.11.0->9.11.1-P1, 9.9.3-S1->9.9.10-S2, 9.10.5-S1->9.10.5-S2. Un atacante que pueda enviar y recibir mensajes a un servidor DNS autoritativo y que conozca un nombre de clave TSIG válido podría ser capaz de omitir la autenticación TSIG de las peticiones AXFE mediante un paquete de petición cuidadosamente construido. Un servidor que solo depende de las claves TSIG para protegerse sin ningún otro mecanismo de protección de listas de control de acceso podría manipularse para: proporcionar el AXFR de una zona a un destinatario no autorizado o aceptar paquetes NOTIFY falsos. • http://www.securityfocus.com/bid/99339 http://www.securitytracker.com/id/1038809 https://access.redhat.com/errata/RHSA-2017:1679 https://access.redhat.com/errata/RHSA-2017:1680 https://h20566.www2.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbux03772en_us https://kb.isc.org/docs/aa-01504 https://security.netapp.com/advisory/ntap-20190830-0003 https://www.debian.org/security/2017/dsa-3904 https://access.redhat.com/security/cve/CVE-2017-3142 https:/ • CWE-20: Improper Input Validation CWE-287: Improper Authentication •
