| CVE-2024-4076 | Hig | 0.49 | 7.5 | 0.02 | Jul 23, 2024 | Client queries that trigger serving stale data and that also require lookups in local authoritative zone data may result in an assertion failure. This issue affects BIND 9 versions 9.16.13 through 9.16.50, 9.18.0 through 9.18.27, 9.19.0 through 9.19.24, 9.11.33-S1 through… | ||
| CVE-2024-1975 | Hig | 0.49 | 7.5 | 0.02 | Jul 23, 2024 | If a server hosts a zone containing a "KEY" Resource Record, or a resolver DNSSEC-validates a "KEY" Resource Record from a DNSSEC-signed domain in cache, a client can exhaust resolver CPU resources by sending a stream of SIG(0) signed requests. This issue affects BIND 9 versions… | ||
| CVE-2024-1737 | Hig | 0.49 | 7.5 | 0.02 | Jul 23, 2024 | Resolver caches and authoritative zone databases that hold significant numbers of RRs for the same hostname (of any RTYPE) can suffer from degraded performance as content is being added or updated, and also when handling client queries for this name. This issue affects BIND 9… | ||
| CVE-2024-0760 | Hig | 0.49 | 7.5 | 0.05 | Jul 23, 2024 | A malicious client can send many DNS messages over TCP, potentially causing the server to become unstable while the attack is in progress. The server may recover after the attack ceases. Use of ACLs will not mitigate the attack. This issue affects BIND 9 versions 9.18.1 through… | ||
| CVE-2023-6516 | Hig | 0.49 | 7.5 | 0.01 | Feb 13, 2024 | To keep its cache database efficient, `named` running as a recursive resolver occasionally attempts to clean up the database. It uses several methods, including some that are asynchronous: a small chunk of memory pointing to the cache element that can be cleaned up is first… | ||
| CVE-2023-5679 | Hig | 0.49 | 7.5 | 0.01 | Feb 13, 2024 | A bad interaction between DNS64 and serve-stale may cause `named` to crash with an assertion failure during recursive resolution, when both of these features are enabled. This issue affects BIND 9 versions 9.16.12 through 9.16.45, 9.18.0 through 9.18.21, 9.19.0 through 9.19.19,… | ||
| CVE-2023-5517 | Hig | 0.49 | 7.5 | 0.01 | Feb 13, 2024 | A flaw in query-handling code can cause `named` to exit prematurely with an assertion failure when: - `nxdomain-redirect ;` is configured, and - the resolver receives a PTR query for an RFC 1918 address that would normally result in an authoritative NXDOMAIN… | ||
| CVE-2023-4408 | Hig | 0.49 | 7.5 | 0.01 | Feb 13, 2024 | The DNS message parsing code in `named` includes a section whose computational complexity is overly high. It does not cause problems for typical DNS traffic, but crafted queries and responses may cause excessive CPU load on the affected `named` instance by exploiting this flaw.… | ||
| CVE-2023-4236 | Hig | 0.49 | 7.5 | 0.02 | Sep 20, 2023 | A flaw in the networking code handling DNS-over-TLS queries may cause `named` to terminate unexpectedly due to an assertion failure. This happens when internal data structures are incorrectly reused under significant DNS-over-TLS query load. This issue affects BIND 9 versions… | ||
| CVE-2023-3341 | Hig | 0.49 | 7.5 | 0.03 | Sep 20, 2023 | The code that processes control channel messages sent to `named` calls certain functions recursively during packet parsing. Recursion depth is only limited by the maximum accepted packet size; depending on the environment, this may cause the packet-parsing code to run out of… | ||
| CVE-2023-2911 | Hig | 0.49 | 7.5 | 0.02 | Jun 21, 2023 | If the `recursive-clients` quota is reached on a BIND 9 resolver configured with both `stale-answer-enable yes;` and `stale-answer-client-timeout 0;`, a sequence of serve-stale-related lookups could cause `named` to loop and terminate unexpectedly due to a stack overflow. This… | ||
| CVE-2023-2829 | Hig | 0.49 | 7.5 | 0.01 | Jun 21, 2023 | A `named` instance configured to run as a DNSSEC-validating recursive resolver with the Aggressive Use of DNSSEC-Validated Cache (RFC 8198) option (`synth-from-dnssec`) enabled can be remotely terminated using a zone with a malformed NSEC record. This issue affects BIND 9… | ||
| CVE-2023-2828 | Hig | 0.49 | 7.5 | 0.04 | Jun 21, 2023 | Every `named` instance configured to run as a recursive resolver maintains a cache database holding the responses to the queries it has recently sent to authoritative servers. The size limit for that cache database can be configured using the `max-cache-size` statement in the… | ||
| CVE-2022-3080 | Hig | 0.49 | 7.5 | 0.02 | Sep 21, 2022 | By sending specific queries to the resolver, an attacker can cause named to crash. | ||
| CVE-2022-38178 | Hig | 0.49 | 7.5 | 0.03 | Sep 21, 2022 | By spoofing the target resolver with responses that have a malformed EdDSA signature, an attacker can trigger a small memory leak. It is possible to gradually erode available memory to the point where named crashes for lack of resources. | ||
| CVE-2022-38177 | Hig | 0.49 | 7.5 | 0.03 | Sep 21, 2022 | By spoofing the target resolver with responses that have a malformed ECDSA signature, an attacker can trigger a small memory leak. It is possible to gradually erode available memory to the point where named crashes for lack of resources. | ||
| CVE-2022-2906 | Hig | 0.49 | 7.5 | 0.02 | Sep 21, 2022 | An attacker can leverage this flaw to gradually erode available memory to the point where named crashes for lack of resources. Upon restart the attacker would have to begin again, but nevertheless there is the potential to deny service. | ||
| CVE-2022-1183 | Hig | 0.49 | 7.5 | 0.06 | May 19, 2022 | On vulnerable configurations, the named daemon may, in some circumstances, terminate with an assertion failure. Vulnerable configurations are those that include a reference to http within the listen-on statements in their named.conf. TLS is used by both DNS over TLS (DoT) and… | ||
| CVE-2022-0635 | Hig | 0.49 | 7.5 | 0.01 | Mar 23, 2022 | Versions affected: BIND 9.18.0 When a vulnerable version of named receives a series of specific queries, the named process will eventually terminate due to a failed assertion check. | ||
| CVE-2022-0667 | Hig | 0.49 | 7.5 | 0.01 | Mar 22, 2022 | When the vulnerability is triggered the BIND process will exit. BIND 9.18.0 |
