Name of the Vulnerable Software and Affected Versions
Hickory DNS versions prior to 0.26.2
Description
The DNS-over-HTTPS HTTP/2 server lacks sufficient timeouts or limits for incomplete request bodies. This allows remote attackers to open DoH connections and send incomplete request bodies, holding the connections open to exhaust server memory, leading to resource exhaustion.
Recommendations
Update to version 0.26.2 or later.
