    <p>
    Xpdf, Kpdf and GPdf are PDF file viewers that run under the X
    Window System. Kpdf and GPdf both contain Xpdf code. Kpdf is also part
    of kdegraphics.
    </p>

  <description>
    <p>
    Xpdf, Kpdf and GPdf do not handle a broken table of embedded
    TrueType fonts correctly. After detecting such a table, Xpdf, Kpdf and
    GPdf attempt to reconstruct the information in it by decoding the PDF
    file, which causes the generation of a huge temporary file.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker may cause a Denial of Service by creating a
    specially crafted PDF file, sending it to a CUPS printing system (which
    uses Xpdf), or by enticing a user to open it in Xpdf, Kpdf, or GPdf.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Xpdf users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-text/xpdf-3.00-r10"</code>
    <p>
    All GPdf users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-text/gpdf-2.10.0-r1"</code>
    <p>
    All Kpdf users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=kde-base/kdegraphics-3.3.2-r3"</code>
    <p>
    All KDE Split Ebuild Kpdf users should upgrade to the latest
    version:
    </p>
    <code>
    # emerge --sync
