    <p>
    Limin Wang has located a buffer overflow inside the put_words()
    function in the abcm2ps code.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could convince the victim to download a
    specially-crafted ABC file. Upon execution, this file would trigger the
    buffer overflow and lead to the execution of arbitrary code with the
    permissions of the user running abcm2ps.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All abcm2ps users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=media-sound/abcm2ps-3.7.21"</code>
  </resolution>
