CVSS: 4.9EPSS: 0%CPEs: 12EXPL: 0CVE-2018-5745 – An assertion failure can occur if a trust anchor rolls over to an unsupported key algorithm when using managed-keys
https://notcve.org/view.php?id=CVE-2018-5745
"managed-keys" is a feature which allows a BIND resolver to automatically maintain the keys used by trust anchors which operators configure for use in DNSSEC validation. Due to an error in the managed-keys feature it is possible for a BIND server which uses managed-keys to exit due to an assertion failure if, during key rollover, a trust anchor's keys are replaced with keys which use an unsupported algorithm. Versions affected: BIND 9.9.0 -> 9.10.8-P1, 9.11.0 -> 9.11.5-P1, 9.12.0 -> 9.12.3-P1, and versions 9.9.3-S1 -> 9.11.5-S3 of BIND 9 Supported Preview Edition.

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 •
