    <description>
        <p>The Motion HTTP server does not correctly perform URL decoding. If the HTTP server receives a request for a URL containing an incomplete percent-encoded character, a flaw in parsing results in an infinite loop trying to parse the rest of the character, which eventually results in a denial of service condition when reading out-of-bounds.</p>
    </description>
    <impact type="low">
        <p>A remote attacker can trigger a denial of service condition in Motion.</p>
    </impact>
    <workaround>
        <p>There is no known workaround at this time.</p>
    </workaround>
    <resolution>
        <p>All Motion users should upgrade to the latest version:</p>
        
        <code>
          # emerge --sync
          # emerge --ask --oneshot --verbose ">=media-video/motion-4.3.2"
        </code>
