    <p>
    LinPopUp is a graphical application that acts as a frontend to
    Samba client messaging functions, allowing a Linux desktop to
    communicate with a Microsoft Windows computer that runs Winpopup.

  <description>
    <p>
    Stephen Dranger discovered that LinPopUp contains a buffer
    overflow in string.c, triggered when replying to a remote user message.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could craft a malicious message that, when
    replied using LinPopUp, would exploit the buffer overflow. This would
    result in the execution of arbitrary code with the privileges of the
    user running LinPopUp.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All LinPopUp users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-im/linpopup-2.0.4-r1"</code>
  </resolution>
