  </background>
  <description>
    <p>
    Venustech AD-LAB discovered that an FTP client connected to a
    vulnerable server with passive mode and SSL support can trigger an
    fclose() function call on an uninitialized stream in ftpd.c.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker can send specially crafted FTP data to a server with
    passive mode and SSL support, causing the ftpd daemon to crash.
    </p>
  </impact>
  <workaround>
    <p>
    Disable passive mode or SSL.
    </p>
  </workaround>
  <resolution>
    <p>
    All Netkit FTP Server users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-ftp/netkit-ftpd-0.17-r7&quot;</code>
