  <description>
    <p>
    Niels Heinen has discovered a buffer overflow in the socket_getline()
    function of Newspost, which can be triggered by providing long strings
    that do not end with a newline character.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could setup a malicious NNTP server and entice a
    Newspost user to post to it, leading to the crash of the Newspost
    process and potentially the execution of arbitrary code with the rights
    of the Newspost user.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Newspost users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-nntp/newspost-2.0-r1"</code>
