| CVE-2025-40778 | 1 Isc | 1 Bind 9 | 2025-10-23 | 8.6 High |
| Under certain circumstances, BIND is too lenient when accepting records from answers, allowing an attacker to inject forged data into the cache. This issue affects BIND 9 versions 9.11.0 through 9.16.50, 9.18.0 through 9.18.39, 9.20.0 through 9.20.13, 9.21.0 through 9.21.12, 9.11.3-S1 through 9.16.50-S1, 9.18.11-S1 through 9.18.39-S1, and 9.20.9-S1 through 9.20.13-S1. | ||||
| CVE-2025-8677 | 1 Isc | 1 Bind 9 | 2025-10-23 | 7.5 High |
| Querying for records within a specially crafted zone containing certain malformed DNSKEY records can lead to CPU exhaustion. This issue affects BIND 9 versions 9.18.0 through 9.18.39, 9.20.0 through 9.20.13, 9.21.0 through 9.21.12, 9.18.11-S1 through 9.18.39-S1, and 9.20.9-S1 through 9.20.13-S1. | ||||
| CVE-2025-40780 | 1 Isc | 1 Bind 9 | 2025-10-23 | 8.6 High |
| In specific circumstances, due to a weakness in the Pseudo Random Number Generator (PRNG) that is used, it is possible for an attacker to predict the source port and query ID that BIND will use. This issue affects BIND 9 versions 9.16.0 through 9.16.50, 9.18.0 through 9.18.39, 9.20.0 through 9.20.13, 9.21.0 through 9.21.12, 9.16.8-S1 through 9.16.50-S1, 9.18.11-S1 through 9.18.39-S1, and 9.20.9-S1 through 9.20.13-S1. | ||||
| CVE-2025-8696 | 1 Isc | 1 Stork | 2025-09-11 | 7.5 High |
| If an unauthenticated user sends a large amount of data to the Stork UI, it may cause memory and disk use problems for the system running the Stork server. This issue affects Stork versions 1.0.0 through 2.3.0. | ||||
| CVE-2025-40779 | 1 Isc | 1 Kea | 2025-08-29 | 7.5 High |
| If a DHCPv4 client sends a request with some specific options, and Kea fails to find an appropriate subnet for the client, the `kea-dhcp4` process will abort with an assertion failure. This happens only if the client request is unicast directly to Kea; broadcast messages do not cause the problem. This issue affects Kea versions 2.7.1 through 2.7.9, 3.0.0, and 3.1.0. | ||||
| CVE-2025-40776 | 1 Isc | 1 Bind | 2025-07-22 | 8.6 High |
| A `named` caching resolver that is configured to send ECS (EDNS Client Subnet) options may be vulnerable to a cache-poisoning attack. This issue affects BIND 9 versions 9.11.3-S1 through 9.16.50-S1, 9.18.11-S1 through 9.18.37-S1, and 9.20.9-S1 through 9.20.10-S1. | ||||
| CVE-2025-40777 | 1 Isc | 1 Bind | 2025-07-21 | 7.5 High |
| If a `named` caching resolver is configured with `serve-stale-enable` `yes`, and with `stale-answer-client-timeout` set to `0` (the only allowable value other than `disabled`), and if the resolver, in the process of resolving a query, encounters a CNAME chain involving a specific combination of cached or authoritative records, the daemon will abort with an assertion failure. This issue affects BIND 9 versions 9.20.0 through 9.20.10, 9.21.0 through 9.21.9, and 9.20.9-S1 through 9.20.10-S1. | ||||
| CVE-2025-40775 | 1 Isc | 1 Bind 9 | 2025-06-23 | 7.5 High |
| When an incoming DNS protocol message includes a Transaction Signature (TSIG), BIND always checks it. If the TSIG contains an invalid value in the algorithm field, BIND immediately aborts with an assertion failure. This issue affects BIND 9 versions 9.20.0 through 9.20.8 and 9.21.0 through 9.21.7. | ||||
| CVE-2022-38178 | 5 Debian, Fedoraproject, Isc and 2 more | 8 Debian Linux, Fedora, Bind and 5 more | 2025-05-28 | 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. | ||||
| CVE-2022-38177 | 5 Debian, Fedoraproject, Isc and 2 more | 8 Debian Linux, Fedora, Bind and 5 more | 2025-05-28 | 7.5 High |
| 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 | 1 Isc | 1 Bind | 2025-05-28 | 7.5 High |
| 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-2022-2881 | 1 Isc | 1 Bind | 2025-05-28 | 5.5 Medium |
| The underlying bug might cause read past end of the buffer and either read memory it should not read, or crash the process. | ||||
| CVE-2023-50387 | 8 Fedoraproject, Isc, Microsoft and 5 more | 18 Fedora, Bind, Windows Server 2008 and 15 more | 2025-05-12 | 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-2018-5733 | 4 Canonical, Debian, Isc and 1 more | 9 Ubuntu Linux, Debian Linux, Dhcp and 6 more | 2025-04-25 | 7.5 High |
| A malicious client which is allowed to send very large amounts of traffic (billions of packets) to a DHCP server can eventually overflow a 32-bit reference counter, potentially causing dhcpd to crash. Affects ISC DHCP 4.1.0 -> 4.1-ESV-R15, 4.2.0 -> 4.2.8, 4.3.0 -> 4.3.6, 4.4.0. | ||||
| CVE-2016-9131 | 4 Debian, Isc, Netapp and 1 more | 14 Debian Linux, Bind, Data Ontap Edge and 11 more | 2025-04-20 | 7.5 High |
| named in ISC BIND 9.x before 9.9.9-P5, 9.10.x before 9.10.4-P5, and 9.11.x before 9.11.0-P2 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a malformed response to an RTYPE ANY query. | ||||
| CVE-2016-9444 | 2 Isc, Redhat | 3 Bind, Enterprise Linux, Rhel Eus | 2025-04-20 | N/A |
| named in ISC BIND 9.x before 9.9.9-P5, 9.10.x before 9.10.4-P5, and 9.11.x before 9.11.0-P2 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a crafted DS resource record in an answer. | ||||
| CVE-2016-9147 | 2 Isc, Redhat | 6 Bind, Enterprise Linux, Rhel Aus and 3 more | 2025-04-20 | N/A |
| named in ISC BIND 9.9.9-P4, 9.9.9-S6, 9.10.4-P4, and 9.11.0-P1 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a response containing an inconsistency among the DNSSEC-related RRsets. | ||||
| CVE-2015-8461 | 1 Isc | 1 Bind | 2025-04-12 | N/A |
| Race condition in resolver.c in named in ISC BIND 9.9.8 before 9.9.8-P2 and 9.10.3 before 9.10.3-P2 allows remote attackers to cause a denial of service (INSIST assertion failure and daemon exit) via unspecified vectors. | ||||
| CVE-2016-2774 | 4 Canonical, Debian, Isc and 1 more | 4 Ubuntu Linux, Debian Linux, Dhcp and 1 more | 2025-04-12 | 5.9 Medium |
| ISC DHCP 4.1.x before 4.1-ESV-R13 and 4.2.x and 4.3.x before 4.3.4 does not restrict the number of concurrent TCP sessions, which allows remote attackers to cause a denial of service (INSIST assertion failure or request-processing outage) by establishing many sessions. | ||||
| CVE-2016-2776 | 4 Hp, Isc, Oracle and 1 more | 10 Hp-ux, Bind, Linux and 7 more | 2025-04-12 | N/A |
| buffer.c in named in ISC BIND 9 before 9.9.9-P3, 9.10.x before 9.10.4-P3, and 9.11.x before 9.11.0rc3 does not properly construct responses, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a crafted query. | ||||
