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-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-2015-5470 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-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-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-2016-5427 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-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-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-2015-1868 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-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.
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-2021-36754 1 Powerdns 1 Authoritative Server 2024-11-21 7.5 High
PowerDNS Authoritative Server 4.5.0 before 4.5.1 allows anybody to crash the process by sending a specific query (QTYPE 65535) that causes an out-of-bounds exception.
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).
