| CVE-2014-8601 | 2 Debian, Powerdns | 2 Debian Linux, Recursor | 2024-08-06 | 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-2014-3614 | 1 Powerdns | 1 Powerdns Recursor | 2024-08-06 | 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-2015-5470 | 1 Powerdns | 2 Authoritative, Recursor | 2024-08-06 | 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-2015-5311 | 1 Powerdns | 1 Authoritative | 2024-08-06 | 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-2015-5230 | 2 Debian, Powerdns | 2 Debian Linux, Authoritative | 2024-08-06 | 7.5 High |
| The DNS packet parsing/generation code in PowerDNS (aka pdns) Authoritative Server 3.4.x before 3.4.6 allows remote attackers to cause a denial of service (crash) via crafted query packets. | ||||
| CVE-2015-1868 | 2 Fedoraproject, Powerdns | 3 Fedora, Authoritative, Recursor | 2024-08-06 | 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-2016-7074 | 2 Debian, Powerdns | 3 Debian Linux, Authoritative, Recursor | 2024-08-06 | N/A |
| An issue has been found in PowerDNS before 3.4.11 and 4.0.2, and PowerDNS recursor before 4.0.4, allowing an attacker in position of man-in-the-middle to alter the content of an AXFR because of insufficient validation of TSIG signatures. A missing check that the TSIG record is the last one, leading to the possibility of parsing records that are not covered by the TSIG signature. | ||||
| CVE-2016-7073 | 2 Debian, Powerdns | 3 Debian Linux, Authoritative, Recursor | 2024-08-06 | N/A |
| An issue has been found in PowerDNS before 3.4.11 and 4.0.2, and PowerDNS recursor before 4.0.4, allowing an attacker in position of man-in-the-middle to alter the content of an AXFR because of insufficient validation of TSIG signatures. A missing check of the TSIG time and fudge values was found in AXFRRetriever, leading to a possible replay attack. | ||||
| CVE-2016-7069 | 1 Powerdns | 1 Dnsdist | 2024-08-06 | N/A |
| An issue has been found in dnsdist before 1.2.0 in the way EDNS0 OPT records are handled when parsing responses from a backend. When dnsdist is configured to add EDNS Client Subnet to a query, the response may contain an EDNS0 OPT record that has to be removed before forwarding the response to the initial client. On a 32-bit system, the pointer arithmetic used when parsing the received response to remove that record might trigger an undefined behavior leading to a crash. | ||||
| CVE-2016-7072 | 2 Debian, Powerdns | 2 Debian Linux, Authoritative | 2024-08-06 | N/A |
| An issue has been found in PowerDNS Authoritative Server before 3.4.11 and 4.0.2 allowing a remote, unauthenticated attacker to cause a denial of service by opening a large number of TCP connections to the web server. If the web server runs out of file descriptors, it triggers an exception and terminates the whole PowerDNS process. While it's more complicated for an unauthorized attacker to make the web server run out of file descriptors since its connection will be closed just after being accepted, it might still be possible. | ||||
| CVE-2016-7068 | 2 Debian, Powerdns | 3 Debian Linux, Authoritative, Recursor | 2024-08-06 | N/A |
| 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-2016-6172 | 2 Opensuse, Powerdns | 3 Leap, Opensuse, Authoritative Server | 2024-08-06 | 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-2016-5427 | 1 Powerdns | 1 Authoritative | 2024-08-06 | 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-2016-5426 | 1 Powerdns | 1 Authoritative | 2024-08-06 | 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-2016-2120 | 2 Debian, Powerdns | 2 Debian Linux, Authoritative | 2024-08-05 | N/A |
| An issue has been found in PowerDNS Authoritative Server versions up to and including 3.4.10, 4.0.1 allowing an authorized user to crash the server by inserting a specially crafted record in a zone under their control then sending a DNS query for that record. The issue is due to an integer overflow when checking if the content of the record matches the expected size, allowing an attacker to cause a read past the buffer boundary. | ||||
| CVE-2017-15120 | 2 Debian, Powerdns | 2 Debian Linux, Recursor | 2024-08-05 | N/A |
| An issue has been found in the parsing of authoritative answers in PowerDNS Recursor before 4.0.8, leading to a NULL pointer dereference when parsing a specially crafted answer containing a CNAME of a different class than IN. An unauthenticated remote attacker could cause a denial of service. | ||||
| CVE-2017-15091 | 1 Powerdns | 1 Authoritative | 2024-08-05 | N/A |
| An issue has been found in the API component of PowerDNS Authoritative 4.x up to and including 4.0.4 and 3.x up to and including 3.4.11, where some operations that have an impact on the state of the server are still allowed even though the API has been configured as read-only via the api-readonly keyword. This missing check allows an attacker with valid API credentials to flush the cache, trigger a zone transfer or send a NOTIFY. | ||||
| CVE-2018-1000003 | 1 Powerdns | 1 Recursor | 2024-08-05 | N/A |
| Improper input validation bugs in DNSSEC validators components in PowerDNS version 4.1.0 allow attacker in man-in-the-middle position to deny existence of some data in DNS via packet replay. | ||||
| CVE-2018-16855 | 1 Powerdns | 1 Recursor | 2024-08-05 | N/A |
| An issue has been found in PowerDNS Recursor before version 4.1.8 where a remote attacker sending a DNS query can trigger an out-of-bounds memory read while computing the hash of the query for a packet cache lookup, possibly leading to a crash. | ||||
| CVE-2018-14644 | 1 Powerdns | 1 Recursor | 2024-08-05 | N/A |
| 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. | ||||
