| CVE-2022-40188 | HOCH7.5 | 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. | 23/09/2022 |
| CVE-2022-32983 | MITTEL5.3 | Knot Resolver through 5.5.1 may allow DNS cache poisoning when there is an attempt to limit forwarding actions by filters. | 20/06/2022 |
| CVE-2021-40083 | HOCH7.5 | 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). | 25/08/2021 |
| CVE-2018-1110 | HOCH7.5 | A flaw was found in knot-resolver before version 2.3.0. Malformed DNS messages may cause denial of service. | 30/03/2021 |
| CVE-2020-12667 | HOCH7.5 | 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. | 19/05/2020 |
| CVE-2019-19331 | HOCH7.5 | 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 CPU seconds for each such uncached message. For example, a few thousand A records can be squashed in | 16/12/2019 |
| CVE-2013-5661 | MITTEL5.9 | Cache Poisoning issue exists in DNS Response Rate Limiting. | 05/11/2019 |
| CVE-2019-10191 | HOCH7.5 | 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 attacks against insecure DNS protocol. | 16/07/2019 |
| CVE-2019-10190 | HOCH7.5 | 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 passed through to the client even if its DNSSEC validation failed, instead of sending a SERVFAIL pack | 16/07/2019 |
| CVE-2018-10920 | MITTEL6.8 | Improper input validation bug in DNS resolver component of Knot Resolver before 2.4.1 allows remote attacker to poison cache. | 02/08/2018 |
| CVE-2018-1000002 | NIEDRIG3.7 | 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. | 22/01/2018 |
