MaraDNS 1.3.07.12 and 1.4.08 computes hash values for DNS data without properly restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted queries with the Recursion Desired (RD) bit set. NOTE: this issue exists because of an incomplete fix for CVE-2012-0024.

Security readout for executives and security teams

This CVE describes a denial-of-service weakness in MaraDNS where specially crafted DNS traffic can force predictable hash collisions and consume CPU. The sources identify MaraDNS 1.3.07.12 and 1.4.08. No source in the bundle shows active exploitation or a CVSS score. Exposure is most likely where MaraDNS 1.3.07.12 or 1.4.08 is reachable by untrusted networks and processes DNS queries with recursion desired. The bundle does not identify other affected products or versions. Treat this as a targeted availability risk for legacy MaraDNS deployments. Prioritize externally reachable or business-critical DNS servers first, but do not assume active exploitation from the provided evidence. Mitigation focus: Inventory systems for MaraDNS 1.3.07.12 and 1.4.08.; Check MaraDNS and operating system vendor guidance for corrected packages.; Restrict recursive DNS access to trusted clients where feasible..
