| CVE-2022-3080 | 2 Fedoraproject, Isc | 2 Fedora, Bind | 2024-06-21 | 7.5 High |
| By sending specific queries to the resolver, an attacker can cause named to crash. | ||||
| CVE-2022-2795 | 3 Debian, Fedoraproject, Isc | 3 Debian Linux, Fedora, Bind | 2024-06-20 | 5.3 Medium |
| By flooding the target resolver with queries exploiting this flaw an attacker can significantly impair the resolver's performance, effectively denying legitimate clients access to the DNS resolution service. | ||||
| CVE-2023-50387 | 8 Fedoraproject, Isc, Microsoft and 5 more | 13 Fedora, Bind, Windows Server 2008 and 10 more | 2024-06-10 | 7.5 High |
| Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the "KeyTrap" issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG records. | ||||
| CVE-2023-3341 | 3 Debian, Fedoraproject, Isc | 3 Debian Linux, Fedora, Bind | 2024-02-16 | 7.5 High |
| 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 available stack memory, causing `named` to terminate unexpectedly. Since each incoming control channel message is fully parsed before its contents are authenticated, exploiting this flaw does not require the attacker to hold a valid RNDC key; only network access to the control channel's configured TCP port is necessary. This issue affects BIND 9 versions 9.2.0 through 9.16.43, 9.18.0 through 9.18.18, 9.19.0 through 9.19.16, 9.9.3-S1 through 9.16.43-S1, and 9.18.0-S1 through 9.18.18-S1. | ||||
| CVE-2006-4095 | 3 Apple, Canonical, Isc | 4 Mac Os X, Mac Os X Server, Ubuntu Linux and 1 more | 2024-02-15 | 7.5 High |
| BIND before 9.2.6-P1 and 9.3.x before 9.3.2-P1 allows remote attackers to cause a denial of service (crash) via certain SIG queries, which cause an assertion failure when multiple RRsets are returned. | ||||
| CVE-2009-0265 | 1 Isc | 1 Bind | 2024-02-13 | 7.5 High |
| Internet Systems Consortium (ISC) BIND 9.6.0 and earlier does not properly check the return value from the OpenSSL EVP_VerifyFinal function, which allows remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature, a similar vulnerability to CVE-2008-5077 and CVE-2009-0025. | ||||
| CVE-2001-0497 | 1 Isc | 1 Bind | 2024-02-08 | 7.8 High |
| dnskeygen in BIND 8.2.4 and earlier, and dnssec-keygen in BIND 9.1.2 and earlier, set insecure permissions for a HMAC-MD5 shared secret key file used for DNS Transactional Signatures (TSIG), which allows attackers to obtain the keys and perform dynamic DNS updates. | ||||
| CVE-2023-4236 | 4 Debian, Fedoraproject, Isc and 1 more | 13 Debian Linux, Fedora, Bind and 10 more | 2024-02-01 | 7.5 High |
| 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 9.18.0 through 9.18.18 and 9.18.11-S1 through 9.18.18-S1. | ||||
| CVE-2022-0396 | 4 Fedoraproject, Isc, Netapp and 1 more | 19 Fedora, Bind, H300e and 16 more | 2024-01-21 | 5.3 Medium |
| BIND 9.16.11 -> 9.16.26, 9.17.0 -> 9.18.0 and versions 9.16.11-S1 -> 9.16.26-S1 of the BIND Supported Preview Edition. Specifically crafted TCP streams can cause connections to BIND to remain in CLOSE_WAIT status for an indefinite period of time, even after the client has terminated the connection. | ||||
| CVE-2016-1286 | 7 Canonical, Debian, Fedoraproject and 4 more | 47 Ubuntu Linux, Debian Linux, Fedora and 44 more | 2023-11-30 | 8.6 High |
| named in ISC BIND 9.x before 9.9.8-P4 and 9.10.x before 9.10.3-P4 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a crafted signature record for a DNAME record, related to db.c and resolver.c. | ||||
| CVE-2016-1285 | 7 Canonical, Debian, Fedoraproject and 4 more | 47 Ubuntu Linux, Debian Linux, Fedora and 44 more | 2023-11-30 | 6.8 Medium |
| named in ISC BIND 9.x before 9.9.8-P4 and 9.10.x before 9.10.3-P4 does not properly handle DNAME records when parsing fetch reply messages, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a malformed packet to the rndc (aka control channel) interface, related to alist.c and sexpr.c. | ||||
| CVE-2022-0667 | 2 Isc, Netapp | 17 Bind, H300e, H300e Firmware and 14 more | 2023-11-09 | 7.5 High |
| When the vulnerability is triggered the BIND process will exit. BIND 9.18.0 | ||||
| CVE-2022-0635 | 2 Isc, Netapp | 17 Bind, H300e, H300e Firmware and 14 more | 2023-11-09 | 7.5 High |
| 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-2021-25220 | 5 Fedoraproject, Isc, Juniper and 2 more | 48 Fedora, Bind, Junos and 45 more | 2023-11-09 | 6.8 Medium |
| BIND 9.11.0 -> 9.11.36 9.12.0 -> 9.16.26 9.17.0 -> 9.18.0 BIND Supported Preview Editions: 9.11.4-S1 -> 9.11.36-S1 9.16.8-S1 -> 9.16.26-S1 Versions of BIND 9 earlier than those shown - back to 9.1.0, including Supported Preview Editions - are also believed to be affected but have not been tested as they are EOL. The cache could become poisoned with incorrect records leading to queries being made to the wrong servers, which might also result in false information being returned to clients. | ||||
| CVE-2022-3924 | 1 Isc | 1 Bind | 2023-11-07 | 7.5 High |
| This issue can affect BIND 9 resolvers with `stale-answer-enable yes;` that also make use of the option `stale-answer-client-timeout`, configured with a value greater than zero. If the resolver receives many queries that require recursion, there will be a corresponding increase in the number of clients that are waiting for recursion to complete. If there are sufficient clients already waiting when a new client query is received so that it is necessary to SERVFAIL the longest waiting client (see BIND 9 ARM `recursive-clients` limit and soft quota), then it is possible for a race to occur between providing a stale answer to this older client and sending an early timeout SERVFAIL, which may cause an assertion failure. This issue affects BIND 9 versions 9.16.12 through 9.16.36, 9.18.0 through 9.18.10, 9.19.0 through 9.19.8, and 9.16.12-S1 through 9.16.36-S1. | ||||
| CVE-2022-3736 | 1 Isc | 1 Bind | 2023-11-07 | 7.5 High |
| BIND 9 resolver can crash when stale cache and stale answers are enabled, option `stale-answer-client-timeout` is set to a positive integer, and the resolver receives an RRSIG query. This issue affects BIND 9 versions 9.16.12 through 9.16.36, 9.18.0 through 9.18.10, 9.19.0 through 9.19.8, and 9.16.12-S1 through 9.16.36-S1. | ||||
| CVE-2022-3488 | 1 Isc | 1 Bind | 2023-11-07 | 7.5 High |
| Processing of repeated responses to the same query, where both responses contain ECS pseudo-options, but where the first is broken in some way, can cause BIND to exit with an assertion failure. 'Broken' in this context is anything that would cause the resolver to reject the query response, such as a mismatch between query and answer name. This issue affects BIND 9 versions 9.11.4-S1 through 9.11.37-S1 and 9.16.8-S1 through 9.16.36-S1. | ||||
| CVE-2022-3094 | 1 Isc | 1 Bind | 2023-11-07 | 7.5 High |
| Sending a flood of dynamic DNS updates may cause `named` to allocate large amounts of memory. This, in turn, may cause `named` to exit due to a lack of free memory. We are not aware of any cases where this has been exploited. Memory is allocated prior to the checking of access permissions (ACLs) and is retained during the processing of a dynamic update from a client whose access credentials are accepted. Memory allocated to clients that are not permitted to send updates is released immediately upon rejection. The scope of this vulnerability is limited therefore to trusted clients who are permitted to make dynamic zone changes. If a dynamic update is REFUSED, memory will be released again very quickly. Therefore it is only likely to be possible to degrade or stop `named` by sending a flood of unaccepted dynamic updates comparable in magnitude to a query flood intended to achieve the same detrimental outcome. BIND 9.11 and earlier branches are also affected, but through exhaustion of internal resources rather than memory constraints. This may reduce performance but should not be a significant problem for most servers. Therefore we don't intend to address this for BIND versions prior to BIND 9.16. This issue affects BIND 9 versions 9.16.0 through 9.16.36, 9.18.0 through 9.18.10, 9.19.0 through 9.19.8, and 9.16.8-S1 through 9.16.36-S1. | ||||
| CVE-2022-38178 | 4 Debian, Fedoraproject, Isc and 1 more | 4 Debian Linux, Fedora, Bind and 1 more | 2023-11-07 | 7.5 High |
| 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. | ||||
