| CVE-2016-7068 | 2 Debian, Powerdns | 3 Debian Linux, Authoritative, Recursor | 2026-06-17 | 7.8 HIGH | 5.3 MEDIUM |
| 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. This issue is based on the fact that the PowerDNS server parses all records present in a query regardless of whether they are needed or even legitimate. A specially crafted query containing a large number of records can be used to take advantage of that behaviour. | |||||
| CVE-2015-5470 | 1 Powerdns | 2 Authoritative, Recursor | 2026-06-17 | 7.8 HIGH | 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-2015-1868 | 2 Fedoraproject, Powerdns | 3 Fedora, Authoritative, Recursor | 2026-06-17 | 7.8 HIGH | 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-2014-8601 | 2 Debian, Powerdns | 2 Debian Linux, Recursor | 2026-06-17 | 5.0 MEDIUM | 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-2009-4010 | 1 Powerdns | 1 Recursor | 2026-06-16 | 7.5 HIGH | N/A |
| Unspecified vulnerability in PowerDNS Recursor before 3.1.7.2 allows remote attackers to spoof DNS data via crafted zones. | |||||
| CVE-2009-4009 | 1 Powerdns | 1 Recursor | 2026-06-16 | 10.0 HIGH | 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-2008-3217 | 1 Powerdns | 1 Recursor | 2026-06-16 | 6.8 MEDIUM | 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-2008-1637 | 1 Powerdns | 1 Recursor | 2026-06-16 | 6.8 MEDIUM | 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-2006-4252 | 1 Powerdns | 1 Recursor | 2026-06-16 | 5.0 MEDIUM | 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-2006-4251 | 1 Powerdns | 1 Recursor | 2026-06-16 | 7.5 HIGH | 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. | |||||
