|---|---|---|---|---|---|
| CVE-2026-27854 | 1 Powerdns | 1 Dnsdist | 2026-07-25 | N/A | 4.8 MEDIUM |
| An attacker might be able to trigger a use-after-free by sending crafted DNS queries to a DNSdist using the DNSQuestion:getEDNSOptions method in custom Lua code. In some cases DNSQuestion:getEDNSOptions might refer to a version of the DNS packet that has been modified, thus triggering a use-after-free and potentially a crash resulting in denial of service. | |||||
| CVE-2026-24028 | 1 Powerdns | 1 Dnsdist | 2026-07-25 | N/A | 5.3 MEDIUM |
| An attacker might be able to trigger an out-of-bounds read by sending a crafted DNS response packet, when custom Lua code uses newDNSPacketOverlay to parse DNS packets. The out-of-bounds read might trigger a crash, leading to a denial of service, or access unrelated memory, leading to potential information disclosure. | |||||
| CVE-2026-27853 | 1 Powerdns | 1 Dnsdist | 2026-07-25 | N/A | 5.9 MEDIUM |
| An attacker might be able to trigger an out-of-bounds write by sending crafted DNS responses to a DNSdist using the DNSQuestion:changeName or DNSResponse:changeName methods in custom Lua code. In some cases the rewritten packet might become larger than the initial response and even exceed 65535 bytes, potentially leading to a crash resulting in denial of service. | |||||
| CVE-2026-0397 | 1 Powerdns | 1 Dnsdist | 2026-07-25 | N/A | 3.1 LOW |
| When the internal webserver is enabled (default is disabled), an attacker might be able to trick an administrator logged to the dashboard into visiting a malicious website and extract information about the running configuration from the dashboard. The root cause of the issue is a misconfiguration of the Cross-Origin Resource Sharing (CORS) policy. | |||||
| CVE-2026-24029 | 1 Powerdns | 1 Dnsdist | 2026-07-25 | N/A | 6.5 MEDIUM |
| When the early_acl_drop (earlyACLDrop in Lua) option is disabled (default is enabled) on a DNS over HTTPs frontend using the nghttp2 provider, the ACL check is skipped, allowing all clients to send DoH queries regardless of the configured ACL. | |||||
| CVE-2026-0396 | 1 Powerdns | 1 Dnsdist | 2026-07-25 | N/A | 3.1 LOW |
| An attacker might be able to inject HTML content into the internal web dashboard by sending crafted DNS queries to a DNSdist instance where domain-based dynamic rules have been enabled via either DynBlockRulesGroup:setSuffixMatchRule or DynBlockRulesGroup:setSuffixMatchRuleFFI. | |||||
| CVE-2026-24030 | 1 Powerdns | 1 Dnsdist | 2026-07-25 | N/A | 5.3 MEDIUM |
| An attacker might be able to trick DNSdist into allocating too much memory while processing DNS over QUIC or DNS over HTTP/3 payloads, resulting in a denial of service. In setups with a large quantity of memory available this usually results in an exception and the QUIC connection is properly closed, but in some cases the system might enter an out-of-memory state instead and terminate the process. | |||||
| CVE-2026-42002 | 1 Powerdns | 1 Authoritative | 2026-07-23 | N/A | 5.9 MEDIUM |
| Concurrency and locking defects in GSS-TSIG | |||||
| CVE-2026-41999 | 1 Powerdns | 1 Authoritative | 2026-07-23 | N/A | 4.8 MEDIUM |
| Incorrect Behaviour of Views with TCP PROXY Requests | |||||
| CVE-2026-42001 | 1 Powerdns | 1 Authoritative | 2026-07-23 | N/A | 7.5 HIGH |
| Insufficient Validation of Autoprimary SOA Queries | |||||
| CVE-2026-42000 | 1 Powerdns | 1 Authoritative | 2026-07-23 | N/A | 6.8 MEDIUM |
| Insufficient Validation of Names During AXFR | |||||
| CVE-2026-42396 | 1 Powerdns | 1 Authoritative | 2026-07-23 | N/A | 4.9 MEDIUM |
| Insufficient Validation of Member Zone Data May Cause Catalog Zone Transfer to Fail | |||||
| CVE-2026-33611 | 1 Powerdns | 1 Authoritative | 2026-06-17 | N/A | 6.5 MEDIUM |
| An operator allowed to use the REST API can cause the Authoritative server to produce invalid HTTPS or SVCB record data, which can in turn cause LMDB database corruption, if using the LMDB backend. | |||||
| CVE-2026-33610 | 1 Powerdns | 1 Authoritative | 2026-06-17 | N/A | 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 | 2026-06-17 | N/A | 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 | 2026-06-17 | N/A | 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 | 2026-06-17 | 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-2026-33601 | 1 Powerdns | 1 Recursor | 2026-06-17 | 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. | |||||
| CVE-2026-33600 | 1 Powerdns | 1 Recursor | 2026-06-17 | N/A | 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-2026-33599 | 1 Powerdns | 1 Dnsdist | 2026-06-17 | 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. | |||||
