    <impact type="normal">
        <p>Bitcoin Core, when debug mode is not used, allows attackers to cause a denial of service (CPU consumption) because draining the inventory-to-send queue is inefficient, as exploited in the wild in May 2023.</p>

        <p>There is no known workaround at this time.</p>
    </workaround>
    <resolution>

          # emerge --ask --oneshot --verbose ">=net-p2p/bitcoind-25.0"
        </code>
