CVSS: 5.3EPSS: 0%CPEs: 15EXPL: 0CVE-2019-6465 – Zone transfer controls for writable DLZ zones were not effective
https://notcve.org/view.php?id=CVE-2019-6465
Controls for zone transfers may not be properly applied to Dynamically Loadable Zones (DLZs) if the zones are writable Versions affected: BIND 9.9.0 -> 9.10.8-P1, 9.11.0 -> 9.11.5-P2, 9.12.0 -> 9.12.3-P2, and versions 9.9.3-S1 -> 9.11.5-S3 of BIND 9 Supported Preview Edition. Versions 9.13.0 -> 9.13.6 of the 9.13 development branch are also affected. Versions prior to BIND 9.9.0 have not been evaluated for vulnerability to CVE-2019-6465. Los controles para las transferencias de zona pueden no ser aplicados correctamente en Dynamically Loadable Zones (DLZs) si las zonas son grabables. Versiones afectadas: BIND 9.9.0 hasta 9.10.8-P1, 9.11.0 hasta 9.11.5-P2, 9.12.0 hasta 9.12.3-P2, y versiones 9.9.3-S1 hasta 9.11.5-S3 de BIND 9 Supported Preview Edition. • https://access.redhat.com/errata/RHSA-2019:3552 https://kb.isc.org/docs/cve-2019-6465 https://access.redhat.com/security/cve/CVE-2019-6465 https://bugzilla.redhat.com/show_bug.cgi?id=1679304 • CWE-284: Improper Access Control CWE-732: Incorrect Permission Assignment for Critical Resource •
CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 0CVE-2018-5742 – An oversight while backporting a feature leads to an assertion failure in buffer.c:420
https://notcve.org/view.php?id=CVE-2018-5742
While backporting a feature for a newer branch of BIND9, RedHat introduced a path leading to an assertion failure in buffer.c:420. Affects RedHat versions bind-9.9.4-65.el7 -> bind-9.9.4-72.el7. No ISC releases are affected. Other packages from other distributions who made the same error may also be affected. Mientras se ejecuta un backport de una característica para una nueva rama de BIND9, RedHat introdujo una ruta que conlleva a un fallo de aserción en buffer.c:420. • https://access.redhat.com/security/cve/cve-2018-5742 https://access.redhat.com/security/cve/CVE-2018-5742 https://bugzilla.redhat.com/show_bug.cgi?id=1655844 • CWE-400: Uncontrolled Resource Consumption CWE-617: Reachable Assertion •

https://notcve.org/view.php?id=CVE-2018-5736
An error in zone database reference counting can lead to an assertion failure if a server which is running an affected version of BIND attempts several transfers of a slave zone in quick succession. This defect could be deliberately exercised by an attacker who is permitted to cause a vulnerable server to initiate zone transfers (for example: by sending valid NOTIFY messages), causing the named process to exit after failing the assertion test. Affects BIND 9.12.0 and 9.12.1. Un error en el conteo de la base de datos de la zona puede conducir a un fallo de aserción si un servidor que está ejecutando una versión afectada de BIND intenta realizar varias transferencias hacia una zona esclava en rápida sucesión. Este defecto podría ser aprovechado deliberadamente por un atacante al que se le permite hacer que un servidor vulnerable inicie transferencias de zona (por ejemplo, mediante el envío de mensajes NOTIFY válidos), lo que provoca que el proceso named se cierre tras fallar la prueba de aserción. • http://www.securityfocus.com/bid/104386 http://www.securitytracker.com/id/1040941 https://kb.isc.org/docs/aa-01602 https://security.netapp.com/advisory/ntap-20180926-0004 • CWE-617: Reachable Assertion •
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: 1%CPEs: 6EXPL: 0CVE-2018-5734 – A malformed request can trigger an assertion failure in badcache.c
https://notcve.org/view.php?id=CVE-2018-5734
While handling a particular type of malformed packet BIND erroneously selects a SERVFAIL rcode instead of a FORMERR rcode. If the receiving view has the SERVFAIL cache feature enabled, this can trigger an assertion failure in badcache.c when the request doesn't contain all of the expected information. Affects BIND 9.10.5-S1 to 9.10.5-S4, 9.10.6-S1, 9.10.6-S2. Al gestionar un tipo concreto de paquete mal formado, BIND selecciona erróneamente un rcode SERVFAIL en lugar de un rcode FORMERR. Si la vista que se está recibiendo tiene la característica de caché SERVFAIL habilitada, esto puede desencadenar un fallo de aserción en badcache.c cuando la petición no contiene toda la información esperada. • http://www.securityfocus.com/bid/103189 http://www.securitytracker.com/id/1040438 https://kb.isc.org/docs/aa-01562 https://security.netapp.com/advisory/ntap-20180926-0005 • CWE-617: Reachable Assertion •
