| CVE-2026-33259 | 1 Powerdns | 1 Recursor | 2026-06-17 | N/A | 5.0 MEDIUM |
| Having many concurrent transfers of the same RPZ can lead to inconsistent RPZ data, use after free and/or a crash of the recursor. Normally concurrent transfers of the same RPZ zone can only occur with a malfunctioning RPZ provider. | |||||
| CVE-2026-33258 | 1 Powerdns | 1 Recursor | 2026-06-17 | N/A | 5.3 MEDIUM |
| By publishing and querying a crafted zone an attacker can cause allocation of large entries in the negative and aggressive NSEC(3) caches. | |||||
| CVE-2026-33257 | 1 Powerdns | 3 Authoritative, Dnsdist, Recursor | 2026-06-17 | N/A | 5.3 MEDIUM |
| An attacker can send a web request that causes unlimited memory allocation in the internal web server, leading to a denial of service. The internal web server is disabled by default. | |||||
| CVE-2026-33256 | 1 Powerdns | 1 Recursor | 2026-06-17 | N/A | 5.3 MEDIUM |
| An attacker can send a web request that causes unlimited memory allocation in the internal web server, leading to a denial of service. The internal web server is disabled by default. | |||||
| CVE-2026-24027 | 1 Powerdns | 1 Recursor | 2026-06-17 | N/A | 5.3 MEDIUM |
| Crafted zones can lead to increased incoming network traffic. | |||||
| CVE-2026-0398 | 1 Powerdns | 1 Recursor | 2026-06-17 | N/A | 5.3 MEDIUM |
| Crafted zones can lead to increased resource usage and crafted CNAME chains can lead to cache poisoning in Recursor. | |||||
| CVE-2025-59030 | 1 Powerdns | 1 Recursor | 2026-06-17 | N/A | 7.5 HIGH |
| An attacker can trigger the removal of cached records by sending a NOTIFY query over TCP. | |||||
| CVE-2025-59029 | 1 Powerdns | 1 Recursor | 2026-06-17 | N/A | 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-2025-59024 | 1 Powerdns | 1 Recursor | 2026-06-17 | N/A | 6.5 MEDIUM |
| Crafted delegations or IP fragments can poison cached delegations in Recursor. | |||||
| CVE-2025-59023 | 1 Powerdns | 1 Recursor | 2026-06-17 | N/A | 8.2 HIGH |
| Crafted delegations or IP fragments can poison cached delegations in Recursor. | |||||
| CVE-2023-50868 | 6 Debian, Fedoraproject, Isc and 3 more | 14 Debian Linux, Fedora, Bind and 11 more | 2026-06-17 | N/A | 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 | 13 Fedora, Bind, Windows Server 2008 and 10 more | 2026-06-17 | N/A | 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-2023-26437 | 1 Powerdns | 1 Recursor | 2026-06-17 | N/A | 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-2023-22617 | 1 Powerdns | 1 Recursor | 2026-06-17 | N/A | 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-2022-37428 | 2 Fedoraproject, Powerdns | 2 Fedora, Recursor | 2026-06-17 | N/A | 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. | |||||
