    records at no-ip.com.

  <description>
    <p>
    xenomuta found out that the GetNextLine() function in noip2.c misses a
    length check, leading to a stack-based buffer overflow.
    </p>
  </description>
  <impact type="high">
    <p>
    A remote attacker could exploit this vulnerability to execute arbitrary
    code by sending a specially crafted HTTP message to the client. NOTE:
    Successful exploitation requires a man in the middle attack, a DNS
    spoofing attack or a compromise of no-ip.com servers.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All noip-updater users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-dns/noip-updater-2.1.9"</code>
