Aliases: CVE-2025-30192 |
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-2016-7073
|
| VCID-2eyk-9hmz-xybp | 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-2025-30195
|
| VCID-2hee-f8gq-rycf | An issue has been found in PowerDNS Recursor versions 4.1.x before 4.1.9 where records in the answer section of responses received from authoritative servers with the AA flag not set were not properly validated, allowing an attacker to bypass DNSSEC validation. |
CVE-2019-3807
|
| VCID-2m6r-ztcg-gbgu | security update |
CVE-2016-7068
|
| VCID-36qt-fxee-ruae | 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-2023-22617
|
| VCID-3e3b-z5bh-pban | An issue has been found in PowerDNS Recursor 4.1.0 up to and including 4.3.0. It allows an attacker (with enough privileges to change the system's hostname) to cause disclosure of uninitialized memory content via a stack-based out-of-bounds read. It only occurs on systems where gethostname() does not have '\0' termination of the returned string if the hostname is larger than the supplied buffer. (Linux systems are not affected because the buffer is always large enough. OpenBSD systems are not affected because the returned hostname always has '\0' termination.) Under some conditions, this issue can lead to the writing of one '\0' byte out-of-bounds on the stack, causing a denial of service or possibly arbitrary code execution. |
CVE-2020-10030
|
| VCID-4532-4nm8-6qc8 | Multiple vulnerabilities have been found in PowerDNS Recursor, the worst of which may allow execution of arbitrary code. |

|
| VCID-4c2u-n7p5-nfg4 | PowerDNS Authoritative Server 4.1.0 up to 4.1.4 inclusive and PowerDNS Recursor 4.0.0 up to 4.1.4 inclusive are vulnerable to a packet cache pollution via crafted query that can lead to denial of service. |
CVE-2018-14626
|
| VCID-66sa-bc5p-jqde | Multiple vulnerabilities have been discovered in Dnsmasq, the worst of which could lead to a denial of service. |
CVE-2023-50387
|
| VCID-67tu-cpzn-t7ep | Use of insufficient randomness in PowerDNS Recursor might lead to DNS cache poisoning. |
CVE-2008-3217
|
| VCID-7dc3-qdk8-k7b2 | 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-2022-27227
|
| VCID-829g-d7jw-sych | A crafted response from an upstream server the recursor has been configured to forward-recurse to can cause a Denial of Service in the Recursor. The default configuration of the Recursor does not use recursive forwarding and is not affected. |
CVE-2024-25583
|
| VCID-8hf9-emba-wbdq | Multiple vulnerabilities have been found in PowerDNS Recursor, the worst of which may allow execution of arbitrary code. |
CVE-2009-4010
|
| VCID-8tar-s444-zfac | 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-2022-37428
|
| VCID-9p7x-52ad-vbh6 | An issue has been found in PowerDNS Recursor from 4.0.0 up to and including 4.1.4. A remote attacker sending a DNS query for a meta-type like OPT can lead to a zone being wrongly cached as failing DNSSEC validation. It only arises if the parent zone is signed, and all the authoritative servers for that parent zone answer with FORMERR to a query for at least one of the meta-types. As a result, subsequent queries from clients requesting DNSSEC validation will be answered with a ServFail. |
CVE-2018-14644
|
| VCID-a7xd-fyh3-xuaq | An issue has been found in the DNSSEC parsing code of PowerDNS Recursor from 4.0.0 up to and including 4.0.6 leading to a memory leak when parsing specially crafted DNSSEC ECDSA keys. These keys are only parsed when validation is enabled by setting dnssec to a value other than off or process-no-validate (default). |
CVE-2017-15094
|
| VCID-bb3a-3ehq-8bhd | 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. |
