CVE-2026-71194 1 Openstack 1 Designate 2026-08-13 6.8 Medium
In OpenStack Designate before 22.0.2, the mDNS handler performs pool-blind lookups when resolving record queries and NOTIFY requests. When two zones with the same name exist across different pools, the lookup fails with a deterministic error, causing the handler to return REFUSED for all DNS queries through that path. The _handle_notify path is exploitable via a single unauthenticated UDP packet. This is independently reachable through the cross-tenant zone overlap described in a different recent CVE, and also affects legitimate same-tenant cross-pool configurations. BIND9 views do not mitigate this issue as mDNS is a shared service upstream of any view configuration.
CVE-2026-71193 1 Openstack 1 Designate 2026-08-13 9.6 Critical
In OpenStack Designate before 22.0.1, zone creation checks (_is_subzone, _is_superzone, and the duplicate-zone DB constraint) are scoped to the target pool only. An authenticated user can bypass these checks by scheduling a zone to a different pool via the AttributeFilter scheduler, creating an overlapping zone that conflicts with another tenant's zone. This enables cross-tenant DNS hijack (redirecting traffic to attacker-controlled IPs) and DNS denial of service (NODATA responses). Exploitation requires a multi-pool deployment with AttributeFilter enabled in scheduler_filters, which is a non-default but documented and supported configuration for self-service tiering.
CVE-2015-5695 1 Openstack 1 Designate 2025-04-20 N/A
Designate 2015.1.0 through 1.0.0.0b1 as packaged in OpenStack Kilo does not enforce RecordSets per domain, and Records per RecordSet quotas when processing an internal zone file transfer, which might allow remote attackers to cause a denial of service (infinite loop) via a crafted resource record set.
CVE-2015-5694 3 Debian, Openstack, Redhat 3 Debian Linux, Designate, Enterprise Linux Openstack Platform 2024-11-21 6.5 Medium
Designate does not enforce the DNS protocol limit concerning record set sizes
