  </description>
  <impact type="normal">
    <p>A remote attacker, able to connect to a Redis instance, could send a
      malicious crafted large request possibly resulting in the execution of
      arbitrary code with the privileges of the process or a Denial of Service
      condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All Redis 5.x users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=dev-db/redis-5.0.12"
    </code>
    
    <p>All Redis 6.x users should upgrade to the latest version:</p>

      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=dev-db/redis-6.0.12"
