| CVE-2020-25829 | 2 Opensuse, Powerdns | 3 Backports Sle, Leap, Recursor | 2022-06-15 | 5.0 MEDIUM | 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). | |||||
| CVE-2020-12244 | 4 Debian, Fedoraproject, Opensuse and 1 more | 5 Debian Linux, Fedora, Backports Sle and 2 more | 2022-04-26 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
| CVE-2020-10995 | 4 Debian, Fedoraproject, Opensuse and 1 more | 5 Debian Linux, Fedora, Backports Sle and 2 more | 2022-04-26 | 5.0 MEDIUM | 7.5 HIGH |
| PowerDNS Recursor from 4.1.0 up to and including 4.3.0 does not sufficiently defend against amplification attacks. An issue in the DNS protocol has been found that allow malicious parties to use recursive DNS services to attack third party authoritative name servers. The attack uses a crafted reply by an authoritative name server to amplify the resulting traffic between the recursive and other authoritative name servers. Both types of service can suffer degraded performance as an effect. This is triggered by random subdomains in the NSDNAME in NS records. PowerDNS Recursor 4.1.16, 4.2.2 and 4.3.1 contain a mitigation to limit the impact of this DNS protocol issue. | |||||

| CVE-2018-1046 | 1 Powerdns | 1 Pdns | 2020-08-31 | 9.3 HIGH | 7.8 HIGH |
| pdns before version 4.1.2 is vulnerable to a buffer overflow in dnsreplay. In the dnsreplay tool provided with PowerDNS Authoritative, replaying a specially crafted PCAP file can trigger a stack-based buffer overflow, leading to a crash and potentially arbitrary code execution. This buffer overflow only occurs when the -ecs-stamp option of dnsreplay is used. | |||||
| CVE-2020-10030 | 1 Powerdns | 1 Recursor | 2020-06-14 | 6.5 MEDIUM | 8.8 HIGH |
| An issue has been found in PowerDNS Recursor 4.1.0 up to and including 4.3.0. It allows an attacker (with enough privileges to change the system's hostname) to cause disclosure of uninitialized memory content via a stack-based out-of-bounds read. It only occurs on systems where gethostname() does not have '\0' termination of the returned string if the hostname is larger than the supplied buffer. (Linux systems are not affected because the buffer is always large enough. OpenBSD systems are not affected because the returned hostname always has '\0' termination.) Under some conditions, this issue can lead to the writing of one '\0' byte out-of-bounds on the stack, causing a denial of service or possibly arbitrary code execution. | |||||
| CVE-2015-5230 | 2 Debian, Powerdns | 2 Debian Linux, Authoritative | 2020-01-17 | 5.0 MEDIUM | 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-2018-14663 | 1 Powerdns | 1 Dnsdist | 2019-10-09 | 4.3 MEDIUM | 5.9 MEDIUM |
| An issue has been found in PowerDNS DNSDist before 1.3.3 allowing a remote attacker to craft a DNS query with trailing data such that the addition of a record by dnsdist, for example an OPT record when adding EDNS Client Subnet, might result in the trailing data being smuggled to the backend as a valid record while not seen by dnsdist. This is an issue when dnsdist is deployed as a DNS Firewall and used to filter some records that should not be received by the backend. This issue occurs only when either the 'useClientSubnet' or the experimental 'addXPF' parameters are used when declaring a new backend. | |||||
| CVE-2018-14644 | 1 Powerdns | 1 Recursor | 2019-10-09 | 4.3 MEDIUM | 5.9 MEDIUM |
| 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. | |||||
| CVE-2018-14626 | 1 Powerdns | 2 Authoritative, Recursor | 2019-10-09 | 5.0 MEDIUM | 7.5 HIGH |
| PowerDNS Authoritative Server 4.1.0 up to 4.1.4 inclusive and PowerDNS Recursor 4.0.0 up to 4.1.4 inclusive are vulnerable to a packet cache pollution via crafted query that can lead to denial of service. | |||||

| CVE-2017-15093 | 1 Powerdns | 1 Recursor | 2019-10-09 | 3.5 LOW | 5.3 MEDIUM |
| When api-config-dir is set to a non-empty value, which is not the case by default, the API in PowerDNS Recursor 4.x up to and including 4.0.6 and 3.x up to and including 3.7.4 allows an authorized user to update the Recursor's ACL by adding and removing netmasks, and to configure forward zones. It was discovered that the new netmask and IP addresses of forwarded zones were not sufficiently validated, allowing an authenticated user to inject new configuration directives into the Recursor's configuration. | |||||
| CVE-2017-15094 | 1 Powerdns | 1 Recursor | 2019-10-09 | 4.3 MEDIUM | 5.9 MEDIUM |
| An issue has been found in the DNSSEC parsing code of PowerDNS Recursor from 4.0.0 up to and including 4.0.6 leading to a memory leak when parsing specially crafted DNSSEC ECDSA keys. These keys are only parsed when validation is enabled by setting dnssec to a value other than off or process-no-validate (default). | |||||
| CVE-2017-15090 | 1 Powerdns | 1 Recursor | 2019-10-09 | 4.3 MEDIUM | 5.9 MEDIUM |
| An issue has been found in the DNSSEC validation component of PowerDNS Recursor from 4.0.0 and up to and including 4.0.6, where the signatures might have been accepted as valid even if the signed data was not in bailiwick of the DNSKEY used to sign it. This allows an attacker in position of man-in-the-middle to alter the content of records by issuing a valid signature for the crafted records. | |||||
| CVE-2017-15091 | 1 Powerdns | 1 Authoritative | 2019-10-09 | 5.5 MEDIUM | 7.1 HIGH |
| 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-2017-15092 | 1 Powerdns | 1 Recursor | 2019-10-09 | 4.3 MEDIUM | 6.1 MEDIUM |
| A cross-site scripting issue has been found in the web interface of PowerDNS Recursor from 4.0.0 up to and including 4.0.6, where the qname of DNS queries was displayed without any escaping, allowing a remote attacker to inject HTML and Javascript code into the web interface, altering the content. | |||||
| CVE-2016-7068 | 2 Debian, Powerdns | 3 Debian Linux, Authoritative, Recursor | 2019-10-09 | 7.8 HIGH | 7.5 HIGH |
| 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-2016-7074 | 2 Debian, Powerdns | 3 Debian Linux, Authoritative, Recursor | 2019-10-09 | 4.3 MEDIUM | 5.9 MEDIUM |
| 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 | 2019-10-09 | 4.3 MEDIUM | 5.9 MEDIUM |
| 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-2016-7072 | 2 Debian, Powerdns | 2 Debian Linux, Authoritative | 2019-10-09 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2016-7069 | 1 Powerdns | 1 Dnsdist | 2019-10-09 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2016-2120 | 2 Debian, Powerdns | 2 Debian Linux, Authoritative | 2019-10-09 | 4.0 MEDIUM | 6.5 MEDIUM |
| 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-2019-3871 | 2 Fedoraproject, Powerdns | 2 Fedora, Authoritative Server | 2019-04-05 | 6.5 MEDIUM | 8.8 HIGH |
| A vulnerability was found in PowerDNS Authoritative Server before 4.0.7 and before 4.1.7. An insufficient validation of data coming from the user when building a HTTP request from a DNS query in the HTTP Connector of the Remote backend, allowing a remote user to cause a denial of service by making the server connect to an invalid endpoint, or possibly information disclosure by making the server connect to an internal endpoint and somehow extracting meaningful information about the response | |||||
