    similar to the famous Civilization series.

  <description>
    <p>
    Luigi Auriemma discovered that Freeciv could be tricked into the
    allocation of enormous chunks of memory when trying to uncompress
    malformed data packages, possibly leading to an out of memory condition
    which causes Freeciv to crash or freeze.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could exploit this issue to cause a Denial of
    Service by sending specially crafted data packages to the Freeciv game
    server.
    </p>
  </impact>
  <workaround>
    <p>
    Play solo games or restrict your multiplayer games to trusted
    parties.
    </p>
  </workaround>
  <resolution>
    <p>
    All Freeciv users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=games-strategy/freeciv-2.0.8"</code>
