| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2024-02-14 | CVE-2023-50387 | Allocation of Resources Without Limits or Throttling vulnerability in multiple products 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. | 7.5 |
| 2023-01-21 | CVE-2023-22617 | Uncontrolled Recursion vulnerability in Powerdns Recursor 4.8.0 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. | 7.5 |
| 2022-03-25 | CVE-2022-27227 | 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. | 7.5 |
| 2020-05-19 | CVE-2020-10995 | Resource Exhaustion vulnerability in multiple products PowerDNS Recursor from 4.1.0 up to and including 4.3.0 does not sufficiently defend against amplification attacks. | 7.5 |
| 2020-05-19 | CVE-2020-10030 | Out-of-bounds Read vulnerability in Powerdns Recursor An issue has been found in PowerDNS Recursor 4.1.0 up to and including 4.3.0. | 8.8 |
| 2020-05-19 | CVE-2020-12244 | Improper Verification of Cryptographic Signature vulnerability in multiple products 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. | 7.5 |
| 2018-09-11 | CVE-2016-7068 | Resource Exhaustion vulnerability in multiple products An issue has been found in PowerDNS before 3.4.11 and 4.0.2, and PowerDNS recursor before 3.7.4 and 4.0.4, allowing a remote, unauthenticated attacker to cause an abnormal CPU usage load on the PowerDNS server by sending crafted DNS queries, which might result in a partial denial of service if the system becomes overloaded. | 7.8 |
| 2015-11-02 | CVE-2015-5470 | Resource Management Errors vulnerability in Powerdns Authoritative and Recursor 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. | 7.8 |
| 2015-05-18 | CVE-2015-1868 | Resource Management Errors vulnerability in multiple products 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. | 7.8 |
| 2010-01-08 | CVE-2009-4010 | Remote Cache Poisoning vulnerability in PowerDNS Recursor Unspecified vulnerability in PowerDNS Recursor before 3.1.7.2 allows remote attackers to spoof DNS data via crafted zones. | 7.5 |
