| CVE | Severidad | EPSS | Explotación activa | Publicada | Descripción |
|---|---|---|---|---|---|
| CVE-2023-50387 | Alta (7.5) | 100% | — | 14 feb 2024 | 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"… |
| CVE-2023-46317 | Alta (7.5) | 0.64% | — | 22 oct 2023 | Knot Resolver before 5.7.0 performs many TCP reconnections upon receiving certain nonsensical responses from servers. |
| CVE-2023-26249 | Alta (7.5) | 0.71% | — | 21 feb 2023 | Knot Resolver before 5.6.0 enables attackers to consume its resources, launching amplification attacks and potentially causing a denial of service. Specifically, a single client query may lead to a hundred TCP… |
| CVE-2022-40188 | Alta (7.5) | 1.9% | — | 23 sept 2022 | Knot Resolver before 5.5.3 allows remote attackers to cause a denial of service (CPU consumption) because of algorithmic complexity. During an attack, an authoritative server must return large NS sets or address sets. |
| CVE-2022-32983 | Media (5.3) | 0.74% | — | 20 jun 2022 | Knot Resolver through 5.5.1 may allow DNS cache poisoning when there is an attempt to limit forwarding actions by filters. |
| CVE-2021-40083 | Alta (7.5) | 1.4% | — | 25 ago 2021 | Knot Resolver before 5.3.2 is prone to an assertion failure, triggerable by a remote attacker in an edge case (NSEC3 with too many iterations used for a positive wildcard proof). |
| CVE-2018-1110 | Alta (7.5) | 1.1% | — | 30 mar 2021 | A flaw was found in knot-resolver before version 2.3.0. Malformed DNS messages may cause denial of service. |
| CVE-2020-12667 | Alta (7.5) | 2.5% | — | 19 may 2020 | Knot Resolver before 5.1.1 allows traffic amplification via a crafted DNS answer from an attacker-controlled server, aka an "NXNSAttack" issue. This is triggered by random subdomains in the NSDNAME in NS records. |
| CVE-2019-19331 | Alta (7.5) | 2.2% | — | 16 dic 2019 | knot-resolver before version 4.3.0 is vulnerable to denial of service through high CPU utilization. DNS replies with very many resource records might be processed very inefficiently, in extreme cases taking even several… |
| CVE-2013-5661 | Media (5.9) | 3.5% | — | 5 nov 2019 | Cache Poisoning issue exists in DNS Response Rate Limiting. |
| CVE-2019-10191 | Alta (7.5) | 1.9% | — | 16 jul 2019 | A vulnerability was discovered in DNS resolver of knot resolver before version 4.1.0 which allows remote attackers to downgrade DNSSEC-secure domains to DNSSEC-insecure state, opening possibility of domain hijack using… |
| CVE-2019-10190 | Alta (7.5) | 2.0% | — | 16 jul 2019 | A vulnerability was discovered in DNS resolver component of knot resolver through version 3.2.0 before 4.1.0 which allows remote attackers to bypass DNSSEC validation for non-existence answer. NXDOMAIN answer would get… |
| CVE-2018-10920 | Media (6.8) | 3.2% | — | 2 ago 2018 | Improper input validation bug in DNS resolver component of Knot Resolver before 2.4.1 allows remote attacker to poison cache. |
| CVE-2018-1000002 | Baja (3.7) | 1.1% | — | 22 ene 2018 | Improper input validation bugs in DNSSEC validators components in Knot Resolver (prior version 1.5.2) allow attacker in man-in-the-middle position to deny existence of some data in DNS via packet replay. |
