| CVE-2019-10162 | 2 Opensuse, Powerdns | 2 Leap, Authoritative | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| A vulnerability has been found in PowerDNS Authoritative Server before versions 4.1.10, 4.0.8 allowing an authorized user to cause the server to exit by inserting a crafted record in a MASTER type zone under their control. The issue is due to the fact that the Authoritative Server will exit when it runs into a parsing error while looking up the NS/A/AAAA records it is about to use for an outgoing notify. | |||||
| CVE-2018-1046 | 1 Powerdns | 1 Pdns | 2024-11-21 | 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-2018-16855 | 1 Powerdns | 1 Recursor | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2018-14663 | 1 Powerdns | 1 Dnsdist | 2024-11-21 | 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 | 2024-11-21 | 4.3 MEDIUM | 5.3 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 | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| 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-2018-10851 | 1 Powerdns | 2 Authoritative, Recursor | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| PowerDNS Authoritative Server 3.3.0 up to 4.1.4 excluding 4.1.5 and 4.0.6, and PowerDNS Recursor 3.2 up to 4.1.4 excluding 4.1.5 and 4.0.9, are vulnerable to a memory leak while parsing malformed records that can lead to remote denial of service. | |||||
| CVE-2018-1000003 | 1 Powerdns | 1 Recursor | 2024-11-21 | 4.3 MEDIUM | 3.7 LOW |
| 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-2017-7557 | 1 Powerdns | 1 Dnsdist | 2024-11-21 | 6.8 MEDIUM | 8.8 HIGH |
| dnsdist version 1.1.0 is vulnerable to a flaw in authentication mechanism for REST API potentially allowing CSRF attack. | |||||
| CVE-2017-15120 | 2 Debian, Powerdns | 2 Debian Linux, Recursor | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2017-15094 | 1 Powerdns | 1 Recursor | 2024-11-21 | 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-2017-15093 | 1 Powerdns | 1 Recursor | 2024-11-21 | 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-2017-15092 | 1 Powerdns | 1 Recursor | 2024-11-21 | 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-2017-15091 | 1 Powerdns | 1 Authoritative | 2024-11-21 | 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-2017-15090 | 1 Powerdns | 1 Recursor | 2024-11-21 | 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-2016-7074 | 2 Debian, Powerdns | 3 Debian Linux, Authoritative, Recursor | 2024-11-21 | 4.3 MEDIUM | 5.3 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 | 2024-11-21 | 4.3 MEDIUM | 5.3 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 | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| 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 | 2024-11-21 | 5.0 MEDIUM | 5.9 MEDIUM |
| 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-2016-7068 | 2 Debian, Powerdns | 3 Debian Linux, Authoritative, Recursor | 2024-11-21 | 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. | |||||
