CVE-2026-42388 1 Powerdns 1 Recursor 2026-06-25 5.9 Medium
Incomplete validation of the SOA record present in a catalog zone might lead to a crash.
CVE-2026-52690 1 Powerdns 1 Recursor 2026-06-25 5.9 Medium
Spoofing replies to Recursor might mark an IP of an authoritative server as not supporting EDNS, causing valdiation of DNSSEC records served by that server to fail.
CVE-2026-42389 1 Powerdns 1 Recursor 2026-06-25 5.3 Medium
This fix provides extra hardening for the 5.4.x branch by doing extra validation of incoming answers from authoritative servers.
CVE-2026-33612 1 Powerdns 1 Recursor 2026-06-25 7.5 High
A malicious authoritative server can send a crafted zone via the ZoneToCache function that leads to cache poisoning.
CVE-2026-40012 1 Powerdns 1 Recursor 2026-06-25 5.3 Medium
ECS zero scoped answers are stored in the packet cache while they should not. This impacts only configurations that have ECS enabled;
CVE-2026-42387 1 Powerdns 1 Recursor 2026-06-25 5.9 Medium
A malicious authoritative server can send a crafted zone via the ZoneToCache function that leads to a crash of the Recursor due to insuffcient input validation.
CVE-2026-42390 1 Powerdns 1 Recursor 2026-06-25 5.3 Medium
An invalid zone might pass ZONEMD validation while it should not. This is only relevant if ZoneToCache is configured with ZONEMD validation.
CVE-2026-33261 1 Powerdns 1 Recursor 2026-04-28 5.9 Medium
A zone transition from NSEC to NSEC3 might trigger an internal inconsistency and cause a denial of service.
CVE-2026-33260 1 Powerdns 3 Authoritative, Dnsdist, Recursor 2026-04-28 5.3 Medium
An attacker can send a web request that causes unlimited memory allocation in the internal web server, leading to a denial of service. The internal web server is disabled by default.
CVE-2026-33258 1 Powerdns 1 Recursor 2026-04-28 5.3 Medium
By publishing and querying a crafted zone an attacker can cause allocation of large entries in the negative and aggressive NSEC(3) caches.
CVE-2026-33256 1 Powerdns 1 Recursor 2026-04-27 5.3 Medium
An attacker can send a web request that causes unlimited memory allocation in the internal web server, leading to a denial of service. The internal web server is disabled by default.
CVE-2026-33257 1 Powerdns 3 Authoritative, Dnsdist, Recursor 2026-04-27 5.3 Medium
An attacker can send a web request that causes unlimited memory allocation in the internal web server, leading to a denial of service. The internal web server is disabled by default.
CVE-2026-33259 1 Powerdns 1 Recursor 2026-04-27 5 Medium
Having many concurrent transfers of the same RPZ can lead to inconsistent RPZ data, use after free and/or a crash of the recursor. Normally concurrent transfers of the same RPZ zone can only occur with a malfunctioning RPZ provider.
CVE-2026-33262 1 Powerdns 1 Recursor 2026-04-27 5.9 Medium
An attacker can send replies that result in a null pointer dereference, caused by a missing consistency check and leading to a denial of service. Cookies are disabled by default.
CVE-2026-33600 1 Powerdns 1 Recursor 2026-04-27 4.4 Medium
An RPZ sent by a malicious authoritative server can result in a null pointer dereference, caused by a missing consistency check and leading to a denial of service.
CVE-2026-33601 1 Powerdns 1 Recursor 2026-04-27 4.4 Medium
If you use the zoneToCache function with a malicious authoritative server, an attacker can send a zone that result in a null pointer dereference, caused by a missing consistency check and leading to a denial of service.
CVE-2006-4251 1 Powerdns 1 Recursor 2026-04-23 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-2008-1637 1 Powerdns 1 Recursor 2026-04-23 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-2009-4010 1 Powerdns 1 Recursor 2026-04-23 N/A
Unspecified vulnerability in PowerDNS Recursor before 3.1.7.2 allows remote attackers to spoof DNS data via crafted zones.
CVE-2008-3217 1 Powerdns 1 Recursor 2026-04-23 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.
