  <description>
    <p>
    Multiple buffer overflows have been reported in OpenTTD, when storing
    long for client names (CVE-2008-3547), in the TruncateString function
    in src/gfx.cpp (CVE-2008-3576) and in src/openttd.cpp when processing a
    large filename supplied to the "-g" parameter in the ttd_main function
    (CVE-2008-3577).
    </p>
  </description>
  <impact type="high">
    <p>
    An authenticated attacker could exploit these vulnerabilities to
    execute arbitrary code with the privileges of the OpenTTD server.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All OpenTTD users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=games-simulation/openttd-0.6.3&quot;</code>
  </resolution>
