| CVE-2009-4010 | 1 Powerdns | 1 Recursor | 2024-11-21 | 7.5 HIGH | N/A |
| Unspecified vulnerability in PowerDNS Recursor before 3.1.7.2 allows remote attackers to spoof DNS data via crafted zones. | |||||
| CVE-2009-4009 | 1 Powerdns | 1 Recursor | 2024-11-21 | 10.0 HIGH | N/A |
| Buffer overflow in PowerDNS Recursor before 3.1.7.2 allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via crafted packets. | |||||
| CVE-2008-3217 | 1 Powerdns | 1 Recursor | 2024-11-21 | 6.8 MEDIUM | 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-2008-1637 | 1 Powerdns | 1 Recursor | 2024-11-21 | 6.8 MEDIUM | 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-2006-4252 | 1 Powerdns | 1 Recursor | 2024-11-21 | 5.0 MEDIUM | N/A |
| PowerDNS Recursor 3.1.3 and earlier allows remote attackers to cause a denial of service (resource exhaustion and application crash) via a CNAME record with a zero TTL, which triggers an infinite loop. | |||||
| CVE-2006-4251 | 1 Powerdns | 1 Recursor | 2024-11-21 | 7.5 HIGH | N/A |
| Buffer overflow in PowerDNS Recursor 3.1.3 and earlier might allow remote attackers to execute arbitrary code via a malformed TCP DNS query that prevents Recursor from properly calculating the TCP DNS query length. | |||||
| CVE-2023-50387 | 8 Fedoraproject, Isc, Microsoft and 5 more | 13 Fedora, Bind, Windows Server 2008 and 10 more | 2024-06-10 | N/A | 7.5 HIGH |
| Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the "KeyTrap" issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG records. | |||||
| CVE-2023-26437 | 1 Powerdns | 1 Recursor | 2024-02-28 | N/A | 5.3 MEDIUM |
| 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-2023-22617 | 1 Powerdns | 1 Recursor | 2024-02-28 | N/A | 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-2022-37428 | 2 Fedoraproject, Powerdns | 2 Fedora, Recursor | 2024-02-28 | N/A | 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 | 2024-02-28 | 4.3 MEDIUM | 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-2020-25829 | 2 Opensuse, Powerdns | 3 Backports Sle, Leap, Recursor | 2024-02-28 | 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-2020-14196 | 1 Powerdns | 1 Recursor | 2024-02-28 | 4.3 MEDIUM | 5.3 MEDIUM |
| In PowerDNS Recursor versions up to and including 4.3.1, 4.2.2 and 4.1.16, the ACL restricting access to the internal web server is not properly enforced. | |||||
| CVE-2020-10995 | 4 Debian, Fedoraproject, Opensuse and 1 more | 5 Debian Linux, Fedora, Backports Sle and 2 more | 2024-02-28 | 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-2020-10030 | 1 Powerdns | 1 Recursor | 2024-02-28 | 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-2020-12244 | 4 Debian, Fedoraproject, Opensuse and 1 more | 5 Debian Linux, Fedora, Backports Sle and 2 more | 2024-02-28 | 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-2018-16855 | 1 Powerdns | 1 Recursor | 2024-02-28 | 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-2016-7074 | 2 Debian, Powerdns | 3 Debian Linux, Authoritative, Recursor | 2024-02-28 | 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 | 2024-02-28 | 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-2018-14644 | 1 Powerdns | 1 Recursor | 2024-02-28 | 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. | |||||
