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
22 Feb 2019 — "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 ... • https://access.redhat.com/errata/RHSA-2019:3552 • CWE-327: Use of a Broken or Risky Cryptographic Algorithm CWE-617: Reachable Assertion •

16 Jan 2019 — 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.

CVSS: 7.5EPSS: 0%CPEs: 4EXPL: 0CVE-2018-5737 – BIND 9.12's serve-stale implementation can cause an assertion failure in rbtdb.c or other undesirable behavior, even if serve-stale is not enabled.
https://notcve.org/view.php?id=CVE-2018-5737
16 Jan 2019 — A problem with the implementation of the new serve-stale feature in BIND 9.12 can lead to an assertion failure in rbtdb.c, even when stale-answer-enable is off. Additionally, problematic interaction between the serve-stale feature and NSEC aggressive negative caching can in some cases cause undesirable behavior from named, such as a recursion loop or excessive logging. Deliberate exploitation of this condition could cause operational problems depending on the particular manifestation -- either degradation o... • http://www.securityfocus.com/bid/104236 • CWE-617: Reachable Assertion •

16 Jan 2019 — 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... • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00041.html • CWE-284: Improper Access Control CWE-863: Incorrect Authorization •

https://notcve.org/view.php?id=CVE-2018-5740
28 Aug 2018 — "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.

13 Jun 2018 — Change #4777 (introduced in October 2017) introduced an unforeseen issue in releases which were issued after that date, affecting which clients are permitted to make recursive queries to a BIND nameserver. The intended (and documented) behavior is that if an operator has not specified a value for the "allow-recursion" setting, it SHOULD default to one of the following: none, if "recursion no;" is set in named.conf; a value inherited from the "allow-query-cache" or "allow-query" settings IF "recursion yes;" ... • http://www.securitytracker.com/id/1041115 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

16 Jan 2018 — 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.
