daemon/worker.c in Unbound 1.x before 1.4.10, when debugging functionality and the interface-automatic option are enabled, allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a crafted DNS request that triggers improper error handling.

Security readout for executives and security teams

Older Unbound DNS servers can be forced to exit if they run a vulnerable 1.x release with debugging and interface-automatic enabled. The business impact is DNS service interruption, not data theft or remote code execution, based on the provided sources. Exposure is limited to Unbound 1.x before 1.4.10 with both debugging functionality and interface-automatic enabled, reachable by remote DNS clients. Current, patched, or differently configured deployments are not shown as affected in the bundle. Treat as a targeted availability risk for legacy DNS infrastructure. Prioritize remediation where affected resolvers are internet-facing, business-critical, or lack automatic restart and monitoring. Mitigation focus: Upgrade Unbound to 1.4.10 or a later vendor-supported release.; Apply relevant vendor package updates, including distribution advisories such as Fedora’s.; Disable debugging functionality where it is not operationally required..
