CVE-2020-24698 1 Powerdns 1 Authoritative 2024-11-21 6.8 MEDIUM 9.8 CRITICAL
An issue was discovered in PowerDNS Authoritative through 4.3.0 when --enable-experimental-gss-tsig is used. A remote, unauthenticated attacker might be able to cause a double-free, leading to a crash or possibly arbitrary code execution. by sending crafted queries with a GSS-TSIG signature.
CVE-2020-24697 1 Powerdns 1 Authoritative 2024-11-21 4.3 MEDIUM 7.5 HIGH
An issue was discovered in PowerDNS Authoritative through 4.3.0 when --enable-experimental-gss-tsig is used. A remote, unauthenticated attacker can cause a denial of service by sending crafted queries with a GSS-TSIG signature.
CVE-2020-24696 1 Powerdns 1 Authoritative 2024-11-21 5.1 MEDIUM 8.1 HIGH
An issue was discovered in PowerDNS Authoritative through 4.3.0 when --enable-experimental-gss-tsig is used. A remote, unauthenticated attacker can trigger a race condition leading to a crash, or possibly arbitrary code execution, by sending crafted queries with a GSS-TSIG signature.
CVE-2020-17482 1 Powerdns 1 Authoritative 2024-11-21 4.0 MEDIUM 4.3 MEDIUM
An issue has been found in PowerDNS Authoritative Server before 4.3.1 where an authorized user with the ability to insert crafted records into a zone might be able to leak the content of uninitialized memory.
CVE-2019-10163 2 Opensuse, Powerdns 3 Backports, Leap, Authoritative 2024-11-21 4.0 MEDIUM 4.3 MEDIUM
A Vulnerability has been found in PowerDNS Authoritative Server before versions 4.1.9, 4.0.8 allowing a remote, authorized master server to cause a high CPU load or even prevent any further updates to any slave zone by sending a large number of NOTIFY messages. Note that only servers configured as slaves are affected by this issue.
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-2018-14626 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-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-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-2016-7068 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.
CVE-2016-5427 1 Powerdns 1 Authoritative 2024-11-21 5.0 MEDIUM 7.5 HIGH
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 2024-11-21 5.0 MEDIUM 7.5 HIGH
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 2024-11-21 4.0 MEDIUM 7.5 HIGH
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-2015-5470 1 Powerdns 2 Authoritative, Recursor 2024-11-21 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-2015-5311 1 Powerdns 1 Authoritative 2024-11-21 5.0 MEDIUM 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 2024-11-21 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-2015-1868 2 Fedoraproject, Powerdns 3 Fedora, Authoritative, Recursor 2024-11-21 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.
