|---|---|---|---|---|
| CVE-2025-30192 | 1 Powerdns | 1 Recursor | 2026-04-15 | 7.5 High |
| An attacker spoofing answers to ECS enabled requests sent out by the Recursor has a chance of success higher than non-ECS enabled queries. The updated version include various mitigations against spoofing attempts of ECS enabled queries by chaining ECS enabled requests and enforcing stricter validation of the received answers. The most strict mitigation done when the new setting outgoing.edns_subnet_harden (old style name edns-subnet-harden) is enabled. | ||||
| CVE-2025-30187 | 1 Powerdns | 1 Dnsdist | 2026-04-15 | 3.7 Low |
| In some circumstances, when DNSdist is configured to use the nghttp2 library to process incoming DNS over HTTPS queries, an attacker might be able to cause a denial of service by crafting a DoH exchange that triggers an unbounded I/O read loop, causing an unexpected consumption of CPU resources. | ||||
| CVE-2026-0396 | 1 Powerdns | 1 Dnsdist | 2026-04-14 | 3.1 Low |
| An attacker might be able to inject HTML content into the internal web dashboard by sending crafted DNS queries to a DNSdist instance where domain-based dynamic rules have been enabled via either DynBlockRulesGroup:setSuffixMatchRule or DynBlockRulesGroup:setSuffixMatchRuleFFI. | ||||
| CVE-2025-59029 | 1 Powerdns | 1 Recursor | 2026-02-19 | 5.3 Medium |
| An attacker can trigger an assertion failure by requesting crafted DNS records, waiting for them to be inserted into the records cache, then send a query with qtype set to ANY. | ||||
| CVE-2025-59030 | 1 Powerdns | 1 Recursor | 2026-02-19 | 7.5 High |
| An attacker can trigger the removal of cached records by sending a NOTIFY query over TCP. | ||||
| CVE-2023-50868 | 6 Debian, Fedoraproject, Isc and 3 more | 19 Debian Linux, Fedora, Bind and 16 more | 2025-12-23 | 7.5 High |
| The Closest Encloser Proof aspect of the DNS protocol (in RFC 5155 when RFC 9276 guidance is skipped) allows remote attackers to cause a denial of service (CPU consumption for SHA-1 computations) via DNSSEC responses in a random subdomain attack, aka the "NSEC3" issue. The RFC 5155 specification implies that an algorithm must perform thousands of iterations of a hash function in certain situations. | ||||
| CVE-2023-50387 | 8 Fedoraproject, Isc, Microsoft and 5 more | 18 Fedora, Bind, Windows Server 2008 and 15 more | 2025-11-04 | 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-2017-7557 | 1 Powerdns | 1 Dnsdist | 2025-04-20 | N/A |
| dnsdist version 1.1.0 is vulnerable to a flaw in authentication mechanism for REST API potentially allowing CSRF attack. | ||||
| CVE-2016-5427 | 1 Powerdns | 1 Authoritative | 2025-04-12 | N/A |
| PowerDNS (aka pdns) Authoritative Server before 3.4.10 does not properly handle a . (dot) inside labels, which allows remote attackers to cause a denial of service (backend CPU consumption) via a crafted DNS query. | ||||
| CVE-2015-5470 | 1 Powerdns | 2 Authoritative, Recursor | 2025-04-12 | N/A |
| The label decompression functionality in PowerDNS Recursor before 3.6.4 and 3.7.x before 3.7.3 and Authoritative (Auth) Server before 3.3.3 and 3.4.x before 3.4.5 allows remote attackers to cause a denial of service (CPU consumption or crash) via a request with a long name that refers to itself. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1868. | ||||
| CVE-2016-6172 | 2 Opensuse, Powerdns | 3 Leap, Opensuse, Authoritative Server | 2025-04-12 | N/A |
| PowerDNS (aka pdns) Authoritative Server before 4.0.1 allows remote primary DNS servers to cause a denial of service (memory exhaustion and secondary DNS server crash) via a large (1) AXFR or (2) IXFR response. | ||||
| CVE-2014-3614 | 1 Powerdns | 1 Powerdns Recursor | 2025-04-12 | N/A |
| Unspecified vulnerability in PowerDNS Recursor (aka pdns_recursor) 3.6.x before 3.6.1 allows remote attackers to cause a denial of service (crash) via an unknown sequence of malformed packets. | ||||
| CVE-2015-1868 | 2 Fedoraproject, Powerdns | 3 Fedora, Authoritative, Recursor | 2025-04-12 | N/A |
| The label decompression functionality in PowerDNS Recursor 3.5.x, 3.6.x before 3.6.3, and 3.7.x before 3.7.2 and Authoritative (Auth) Server 3.2.x, 3.3.x before 3.3.2, and 3.4.x before 3.4.4 allows remote attackers to cause a denial of service (CPU consumption or crash) via a request with a name that refers to itself. | ||||
| CVE-2014-8601 | 2 Debian, Powerdns | 2 Debian Linux, Recursor | 2025-04-12 | N/A |
| PowerDNS Recursor before 3.6.2 does not limit delegation chaining, which allows remote attackers to cause a denial of service ("performance degradations") via a large or infinite number of referrals, as demonstrated by resolving domains hosted by ezdns.it. | ||||
| CVE-2016-5426 | 1 Powerdns | 1 Authoritative | 2025-04-12 | N/A |
| PowerDNS (aka pdns) Authoritative Server before 3.4.10 allows remote attackers to cause a denial of service (backend CPU consumption) via a long qname. | ||||
| CVE-2015-5311 | 1 Powerdns | 1 Authoritative | 2025-04-12 | N/A |
| PowerDNS (aka pdns) Authoritative Server 3.4.4 before 3.4.7 allows remote attackers to cause a denial of service (assertion failure and server crash) via crafted query packets. | ||||
| CVE-2012-1193 | 1 Powerdns | 1 Powerdns Recursor | 2025-04-11 | N/A |
| The resolver in PowerDNS Recursor (aka pdns_recursor) 3.3 overwrites cached server names and TTL values in NS records during the processing of a response to an A record query, which allows remote attackers to trigger continued resolvability of revoked domain names via a "ghost domain names" attack. | ||||
| CVE-2012-0206 | 1 Powerdns | 1 Authoritative Server | 2025-04-11 | N/A |
| common_startup.cc in PowerDNS (aka pdns) Authoritative Server before 2.9.22.5 and 3.x before 3.0.1 allows remote attackers to cause a denial of service (packet loop) via a crafted UDP DNS response. | ||||
| CVE-2023-22617 | 1 Powerdns | 1 Recursor | 2025-04-03 | 7.5 High |
| A remote attacker might be able to cause infinite recursion in PowerDNS Recursor 4.8.0 via a DNS query that retrieves DS records for a misconfigured domain, because QName minimization is used in QM fallback mode. This is fixed in 4.8.1. | ||||
| CVE-2023-26437 | 1 Powerdns | 1 Recursor | 2025-02-13 | 3.4 Low |
| Denial of service vulnerability in PowerDNS Recursor allows authoritative servers to be marked unavailable.This issue affects Recursor: through 4.6.5, through 4.7.4 , through 4.8.3. | ||||
