2022-09-23 CVE-2022-40188 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. Debian_linux, Fedora, Knot_resolver 7.5
2024-02-14 CVE-2023-50387 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. Fedora, Bind, Windows_server_2008, Windows_server_2012, Windows_server_2016, Windows_server_2019, Windows_server_2022, Windows_server_2022_23h2, Knot_resolver, Unbound, Recursor, Enterprise_linux, Dnsmasq 7.5
2023-02-21 CVE-2023-26249 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 connection attempts if a DNS server closes connections without providing a response. Knot_resolver 7.5
2020-05-19 CVE-2020-12667 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. Knot_resolver 7.5
