| 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-2026-33595 | 1 Powerdns | 1 Dnsdist | 2026-10-26 | N/A | 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-2026-33602 | 1 Powerdns | 1 Dnsdist | 2026-10-26 | N/A | 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-2026-33593 | 1 Powerdns | 1 Dnsdist | 2026-10-26 | N/A | 7.5 HIGH |
| A client can trigger a divide by zero error leading to crash by sending a crafted DNSCrypt query. | |||||

| 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-2026-33598 | 1 Powerdns | 1 Dnsdist | 2026-10-26 | N/A | 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-2026-33258 | 1 Powerdns | 1 Recursor | 2026-10-26 | N/A | 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-2026-33599 | 1 Powerdns | 1 Dnsdist | 2026-10-26 | N/A | 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-2026-33254 | 1 Powerdns | 1 Dnsdist | 2026-10-26 | N/A | 5.3 MEDIUM |
| An attacker can create a large number of concurrent DoQ or DoH3 connections, causing unlimited memory allocation in DNSdist and leading to a denial of service. DOQ and DoH3 are disabled by default. | |||||
| CVE-2026-33596 | 1 Powerdns | 1 Dnsdist | 2026-10-26 | N/A | 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-2026-33259 | 1 Powerdns | 1 Recursor | 2026-10-26 | N/A | 5.0 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-2026-33601 | 1 Powerdns | 1 Recursor | 2026-10-26 | N/A | 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. | |||||
