CVE-2008-5277 1 Powerdns 1 Powerdns 2025-04-09 N/A
PowerDNS before 2.9.21.2 allows remote attackers to cause a denial of service (daemon crash) via a CH HINFO query.
CVE-2008-1637 1 Powerdns 1 Recursor 2025-04-09 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-2008-3217 1 Powerdns 1 Recursor 2025-04-09 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-2025-30195 1 Powerdns 1 Recursor 2025-04-07 7.5 High
An attacker can publish a zone containing specific Resource Record Sets. Processing and caching results for these sets can lead to an illegal memory accesses and crash of the Recursor, causing a denial of service. The remedy is: upgrade to the patched 5.2.1 version. We would like to thank Volodymyr Ilyin for bringing this issue to our attention.
CVE-2023-22617 1 Powerdns 1 Recursor 2025-04-03 7.5 High
A remote attacker might be able to cause infinite recursion in PowerDNS Recursor 4.8.0 via a DNS query that retrieves DS records for a misconfigured domain, because QName minimization is used in QM fallback mode. This is fixed in 4.8.1.
CVE-2005-2301 1 Powerdns 1 Powerdns 2025-04-03 N/A
PowerDNS before 2.9.18, when running with an LDAP backend, does not properly escape LDAP queries, which allows remote attackers to cause a denial of service (failure to answer ldap questions) and possibly conduct an LDAP injection attack.
CVE-2005-0428 1 Powerdns 1 Powerdns 2025-04-03 N/A
The DNSPacket::expand method in dnspacket.cc in PowerDNS before 2.9.17 allows remote attackers to cause a denial of service by sending a random stream of bytes.
CVE-2006-2069 1 Powerdns 1 Powerdns 2025-04-03 N/A
The recursor in PowerDNS before 3.0.1 allows remote attackers to cause a denial of service (application crash) via malformed EDNS0 packets.
CVE-2005-0038 1 Powerdns 1 Powerdns 2025-04-03 N/A
The DNS implementation of PowerDNS 2.9.16 and earlier allows remote attackers to cause a denial of service via a compressed DNS packet with a label length byte with an incorrect offset, which could trigger an infinite loop.
CVE-2005-2302 1 Powerdns 1 Powerdns 2025-04-03 N/A
PowerDNS before 2.9.18, when allowing recursion to a restricted range of IP addresses, does not properly handle questions from clients that are denied recursion, which could cause a "blank out" of answers to those clients that are allowed to use recursion.
CVE-2024-25583 1 Powerdns 1 Powerdns 2025-02-13 7.5 High
A crafted response from an upstream server the recursor has been configured to forward-recurse to can cause a Denial of Service in the Recursor. The default configuration of the Recursor does not use recursive forwarding and is not affected.
CVE-2024-25581 1 Powerdns 1 Dnsdist 2025-02-13 7.5 High
When incoming DNS over HTTPS support is enabled using the nghttp2 provider, and queries are routed to a tcp-only or DNS over TLS backend, an attacker can trigger an assertion failure in DNSdist by sending a request for a zone transfer (AXFR or IXFR) over DNS over HTTPS, causing the process to stop and thus leading to a Denial of Service. DNS over HTTPS is not enabled by default, and backends are using plain DNS (Do53) by default.
CVE-2023-26437 1 Powerdns 1 Recursor 2025-02-13 3.4 Low
Denial of service vulnerability in PowerDNS Recursor allows authoritative servers to be marked unavailable.This issue affects Recursor: through 4.6.5, through 4.7.4 , through 4.8.3.
CVE-2024-25590 1 Powerdns 1 Recursor 2024-11-21 7.5 High
An attacker can publish a zone containing specific Resource Record Sets. Repeatedly processing and caching results for these sets can lead to a denial of service.
CVE-2022-37428 2 Fedoraproject, Powerdns 2 Fedora, Recursor 2024-11-21 6.5 Medium
PowerDNS Recursor up to and including 4.5.9, 4.6.2 and 4.7.1, when protobuf logging is enabled, has Improper Cleanup upon a Thrown Exception, leading to a denial of service (daemon crash) via a DNS query that leads to an answer with specific properties.
CVE-2022-27227 2 Fedoraproject, Powerdns 3 Fedora, Authoritative Server, Recursor 2024-11-21 7.5 High
In PowerDNS Authoritative Server before 4.4.3, 4.5.x before 4.5.4, and 4.6.x before 4.6.1 and PowerDNS Recursor before 4.4.8, 4.5.x before 4.5.8, and 4.6.x before 4.6.1, insufficient validation of an IXFR end condition causes incomplete zone transfers to be handled as successful transfers.
CVE-2021-36754 1 Powerdns 1 Authoritative Server 2024-11-21 7.5 High
PowerDNS Authoritative Server 4.5.0 before 4.5.1 allows anybody to crash the process by sending a specific query (QTYPE 65535) that causes an out-of-bounds exception.
CVE-2020-25829 2 Opensuse, Powerdns 3 Backports Sle, Leap, Recursor 2024-11-21 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-2020-24698 1 Powerdns 1 Authoritative 2024-11-21 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 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.
