| CVE-2025-30192 | 1 Powerdns | 1 Recursor | 2025-07-22 | 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-2024-25590 | 1 Powerdns | 1 Recursor | 2025-07-12 | 7.5 High |
| An attacker can publish a zone containing specific Resource Record Sets. Repeatedly processing and caching results for these sets can lead to a denial of service. | ||||
| CVE-2025-30193 | 1 Powerdns | 1 Dnsdist | 2025-07-12 | 7.5 High |
| In some circumstances, when DNSdist is configured to allow an unlimited number of queries on a single, incoming TCP connection from a client, an attacker can cause a denial of service by crafting a TCP exchange that triggers an exhaustion of the stack and a crash of DNSdist, causing a denial of service. The remedy is: upgrade to the patched 1.9.10 version. A workaround is to restrict the maximum number of queries on incoming TCP connections to a safe value, like 50, via the setMaxTCPQueriesPerConnection setting. We would like to thank Renaud Allard for bringing this issue to our attention. | ||||
| CVE-2025-30194 | 1 Powerdns | 1 Dnsdist | 2025-06-20 | 7.5 High |
| When DNSdist is configured to provide DoH via the nghttp2 provider, an attacker can cause a denial of service by crafting a DoH exchange that triggers an illegal memory access (double-free) and crash of DNSdist, causing a denial of service. The remedy is: upgrade to the patched 1.9.9 version. A workaround is to temporarily switch to the h2o provider until DNSdist has been upgraded to a fixed version. We would like to thank Charles Howes for bringing this issue to our attention. | ||||
| CVE-2023-50387 | 8 Fedoraproject, Isc, Microsoft and 5 more | 18 Fedora, Bind, Windows Server 2008 and 15 more | 2025-05-12 | 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-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-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-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-2015-5470 | 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-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-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-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-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-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-2009-4009 | 1 Powerdns | 1 Recursor | 2025-04-09 | N/A |
| Buffer overflow in PowerDNS Recursor before 3.1.7.2 allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via crafted packets. | ||||
| CVE-2006-4252 | 1 Powerdns | 1 Recursor | 2025-04-09 | N/A |
| PowerDNS Recursor 3.1.3 and earlier allows remote attackers to cause a denial of service (resource exhaustion and application crash) via a CNAME record with a zero TTL, which triggers an infinite loop. | ||||
| CVE-2008-1637 | 1 Powerdns | 1 Recursor | 2025-04-09 | N/A |
| PowerDNS Recursor before 3.1.5 uses insufficient randomness to calculate (1) TRXID values and (2) UDP source port numbers, which makes it easier for remote attackers to poison a DNS cache, related to (a) algorithmic deficiencies in rand and random functions in external libraries, (b) use of a 32-bit seed value, and (c) choice of the time of day as the sole seeding information. | ||||
| CVE-2008-3337 | 1 Powerdns | 2 Authoritative Server, Powerdns | 2025-04-09 | N/A |
| PowerDNS Authoritative Server before 2.9.21.1 drops malformed queries, which might make it easier for remote attackers to poison DNS caches of other products running on other servers, a different issue than CVE-2008-1447 and CVE-2008-3217. | ||||
