    <p>
    Erich Schubert from Debian discovered that unp does not escape file
    names properly before passing them to calls of the shell.

  <impact type="normal">
    <p>
    A remote attacker could entice a user or automated system to unpack a
    compressed archive with a specially crafted file name, leading to the
    execution of shell commands from within the filename. That code will be
    executed with the privileges of the user running unp.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All unp users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-arch/unp-1.0.14"</code>
