| 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-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-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-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-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-2008-3217 | 1 Powerdns | 1 Recursor | 2025-04-09 | N/A |
| PowerDNS Recursor before 3.1.6 does not always use the strongest random number generator for source port selection, which makes it easier for remote attack vectors to conduct DNS cache poisoning. NOTE: this is related to incomplete integration of security improvements associated with addressing CVE-2008-1637. | ||||
| 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-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-2009-4010 | 1 Powerdns | 1 Recursor | 2025-04-09 | N/A |
| Unspecified vulnerability in PowerDNS Recursor before 3.1.7.2 allows remote attackers to spoof DNS data via crafted zones. | ||||
| CVE-2006-4251 | 1 Powerdns | 1 Recursor | 2025-04-09 | N/A |
| Buffer overflow in PowerDNS Recursor 3.1.3 and earlier might allow remote attackers to execute arbitrary code via a malformed TCP DNS query that prevents Recursor from properly calculating the TCP DNS query length. | ||||
| 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-2025-30195 | 1 Powerdns | 1 Recursor | 2025-04-07 | 7.5 High |
| An attacker can publish a zone containing specific Resource Record Sets. Processing and caching results for these sets can lead to an illegal memory accesses and crash of the Recursor, causing a denial of service. The remedy is: upgrade to the patched 5.2.1 version. We would like to thank Volodymyr Ilyin for bringing this issue to our attention. | ||||
| 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. | ||||
| CVE-2022-37428 | 2 Fedoraproject, Powerdns | 2 Fedora, Recursor | 2024-11-21 | 6.5 Medium |
| PowerDNS Recursor up to and including 4.5.9, 4.6.2 and 4.7.1, when protobuf logging is enabled, has Improper Cleanup upon a Thrown Exception, leading to a denial of service (daemon crash) via a DNS query that leads to an answer with specific properties. | ||||
| CVE-2022-27227 | 2 Fedoraproject, Powerdns | 3 Fedora, Authoritative Server, Recursor | 2024-11-21 | 7.5 High |
| In PowerDNS Authoritative Server before 4.4.3, 4.5.x before 4.5.4, and 4.6.x before 4.6.1 and PowerDNS Recursor before 4.4.8, 4.5.x before 4.5.8, and 4.6.x before 4.6.1, insufficient validation of an IXFR end condition causes incomplete zone transfers to be handled as successful transfers. | ||||
| CVE-2020-25829 | 2 Opensuse, Powerdns | 3 Backports Sle, Leap, Recursor | 2024-11-21 | 7.5 High |
| An issue has been found in PowerDNS Recursor before 4.1.18, 4.2.x before 4.2.5, and 4.3.x before 4.3.5. A remote attacker can cause the cached records for a given name to be updated to the Bogus DNSSEC validation state, instead of their actual DNSSEC Secure state, via a DNS ANY query. This results in a denial of service for installation that always validate (dnssec=validate), and for clients requesting validation when on-demand validation is enabled (dnssec=process). | ||||
| CVE-2020-14196 | 1 Powerdns | 1 Recursor | 2024-11-21 | 5.3 Medium |
| In PowerDNS Recursor versions up to and including 4.3.1, 4.2.2 and 4.1.16, the ACL restricting access to the internal web server is not properly enforced. | ||||
| CVE-2020-12244 | 4 Debian, Fedoraproject, Opensuse and 1 more | 5 Debian Linux, Fedora, Backports Sle and 2 more | 2024-11-21 | 7.5 High |
| An issue has been found in PowerDNS Recursor 4.1.0 through 4.3.0 where records in the answer section of a NXDOMAIN response lacking an SOA were not properly validated in SyncRes::processAnswer, allowing an attacker to bypass DNSSEC validation. | ||||
