The wire-format parser accepts multi-dname RRs whose RDATA ends after the first name, so an attacker who runs a DNSSEC-signed authoritative server can deliver a record with an absent second domain name (e.g. SOA record) and cause 'query_dname_tolower()' to walk label-by-label through stale bytes in the per-worker 'env->scratch_buffer', past the end of that heap allocation if 'msg-buffer-size' has been lowered from the default. This leads to heap buffer overflow and on a release build the outcome relies heavily on the contents of the buffer tail and the adjacent heap chunk.",

          "details": "This issue only triggers when Unbound validates attacker-controlled, DNSSEC-signed PX/RP/MINFO/SOA data with a deliberately truncated second domain name, and the heap overflow occurs only if the non-default msg-buffer-size has been reduced below the 65,552-byte default. Even then, exploitation is high-complexity and unreliable (dependent on heap layout), with no confidentiality impact and at most low integrity/availability effects, typically just a crash. In centrally managed enterprise resolver deployments that keep default settings, the practical risk is minimal, so this CVE can be safely deprioritized.",
