  <description>
    <p>
    A buffer overflow has been identified in the slc_add_reply()
    function of netkit-telnetd client, where a large number of SLC commands
    can overflow a fixed size buffer.
    </p>
  </description>
  <impact type="normal">
    <p>
    Successful explotation would require a vulnerable user to connect
    to an attacker-controlled host using telnet, potentially executing
    arbitrary code with the permissions of the telnet user.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All netkit-telnetd users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-misc/netkit-telnetd-0.17-r6"</code>
  </resolution>
