| CVE-2019-10191 | 2 Fedoraproject, Nic | 2 Fedora, Knot Resolver | 2025-02-13 | 7.5 High |
| 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. | ||||
| CVE-2019-10190 | 2 Fedoraproject, Nic | 2 Fedora, Knot Resolver | 2025-02-13 | 7.5 High |
| 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 packet. Caching is not affected by this particular bug but see CVE-2019-10191. | ||||
| CVE-2020-12667 | 1 Nic | 1 Knot Resolver | 2024-11-21 | 7.5 High |
| 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 | 2 Debian, Nic | 2 Debian Linux, Knot Resolver | 2024-11-21 | 7.5 High |
| 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 into one DNS message (limit is 64kB). | ||||
| CVE-2018-1110 | 1 Nic | 1 Knot Resolver | 2024-11-21 | 7.5 High |
| A flaw was found in knot-resolver before version 2.3.0. Malformed DNS messages may cause denial of service. | ||||
| CVE-2018-10920 | 1 Nic | 1 Knot Resolver | 2024-11-21 | 6.8 Medium |
| Improper input validation bug in DNS resolver component of Knot Resolver before 2.4.1 allows remote attacker to poison cache. | ||||
| CVE-2018-1000002 | 1 Nic | 1 Knot Resolver | 2024-11-21 | 3.7 Low |
| 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. | ||||
| CVE-2013-5661 | 4 Isc, Nic, Nlnetlabs and 1 more | 4 Bind, Knot Resolver, Nsd and 1 more | 2024-11-21 | 5.9 Medium |
| Cache Poisoning issue exists in DNS Response Rate Limiting. | ||||
