    <p>
    o3read is a standalone converter for OpenOffice.org files. It
    allows a user to dump the contents tree (o3read) and convert to plain
    text (o3totxt) or to HTML (o3tohtml) Writer and Calc files.

  <description>
    <p>
    Wiktor Kopec discovered that the parse_html function in o3read.c
    copies any number of bytes into a 1024-byte t[] array.
    </p>
  </description>
  <impact type="normal">
    <p>
    Using a specially crafted file, possibly delivered by e-mail or
    over the Web, an attacker may execute arbitrary code with the
    permissions of the user running o3read.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All o3read users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-text/o3read-0.0.4"</code>
