|---|---|---|---|---|
| CVE-2026-33610 | 1 Powerdns | 1 Authoritative | 2026-04-24 | 5.9 Medium |
| A rogue primary server may cause file descriptor exhaustion and eventually a denial of service, when a PowerDNS secondary server forwards a DNS update request to it. | ||||
| CVE-2026-33609 | 1 Powerdns | 1 Authoritative | 2026-04-24 | 5.3 Medium |
| Incomplete escaping of LDAP queries when running with 8bit-dns enabled allows users to perform queries of internal domain subtrees. | ||||
| CVE-2026-33608 | 1 Powerdns | 1 Authoritative | 2026-04-24 | 7.4 High |
| An attacker can send a notify request that causes a new secondary domain to be added to the bind backend, but causes said backend to update its configuration to an invalid one, leading to the backend no longer able to run on the next restart, requiring manual operation to fix it. | ||||
| CVE-2026-33602 | 1 Powerdns | 1 Dnsdist | 2026-04-24 | 6.5 Medium |
| A rogue backend can send a crafted UDP response with a query ID off by one related to the maximum configured value, triggering an out-of-bounds write leading to a denial of service. | ||||
| CVE-2026-33599 | 1 Powerdns | 1 Dnsdist | 2026-04-24 | 3.1 Low |
| A rogue backend can send a crafted SVCB response to a Discovery of Designated Resolvers request, when requested via either the autoUpgrade (Lua) option to newServer or auto_upgrade (YAML) settings. DDR upgrade is not enabled by default. | ||||
| CVE-2026-33598 | 1 Powerdns | 1 Dnsdist | 2026-04-24 | 4.8 Medium |
| A cached crafted response can cause an out-of-bounds read if custom Lua code calls getDomainListByAddress() or getAddressListByDomain() on a packet cache. | ||||
| CVE-2026-33597 | 1 Powerdns | 1 Dnsdist | 2026-04-24 | 3.7 Low |
| PRSD detection denial of service | ||||
| CVE-2026-33596 | 1 Powerdns | 1 Dnsdist | 2026-04-24 | 3.1 Low |
| A client might theoretically be able to cause a mismatch between queries sent to a backend and the received responses by sending a flood of perfectly timed queries that are routed to a TCP-only or DNS over TLS backend. | ||||
| CVE-2026-33595 | 1 Powerdns | 1 Dnsdist | 2026-04-24 | 5.3 Medium |
| A client can trigger excessive memory allocation by generating a lot of errors responses over a single DoQ and DoH3 connection, as some resources were not properly released until the end of the connection. | ||||
| CVE-2026-33593 | 1 Powerdns | 1 Dnsdist | 2026-04-24 | 7.5 High |
| A client can trigger a divide by zero error leading to crash by sending a crafted DNSCrypt query. | ||||
| CVE-2026-33594 | 1 Powerdns | 1 Dnsdist | 2026-04-24 | 5.3 Medium |
| A client can trigger excessive memory allocation by generating a lot of queries that are routed to an overloaded DoH backend, causing queries to accumulate into a buffer that will not be released until the end of the connection. | ||||
| CVE-2009-4009 | 1 Powerdns | 1 Recursor | 2026-04-23 | 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-2008-5277 | 1 Powerdns | 1 Powerdns | 2026-04-23 | 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-2008-3217 | 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. | ||||
| 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-2008-3337 | 1 Powerdns | 2 Authoritative Server, Powerdns | 2026-04-23 | N/A |
| PowerDNS Authoritative Server before 2.9.21.1 drops malformed queries, which might make it easier for remote attackers to poison DNS caches of other products running on other servers, a different issue than CVE-2008-1447 and CVE-2008-3217. | ||||
| 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-2006-4252 | 1 Powerdns | 1 Recursor | 2026-04-23 | 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-2026-24027 | 1 Powerdns | 1 Recursor | 2026-04-20 | 5.3 Medium |
| Crafted zones can lead to increased incoming network traffic. | ||||
