    Poppler is a cross-platform PDF rendering library originally based on
    Xpdf. KOffice is an integrated office suite for KDE. KWord is the
    KOffice word processor. KPDF is a KDE-based PDF viewer included in the
    kdegraphics package.

    <p>
    Alin Rad Pop (Secunia Research) discovered several vulnerabilities in
    the "Stream.cc" file of Xpdf: An integer overflow in the
    DCTStream::reset() method and a boundary error in the
    CCITTFaxStream::lookChar() method, both leading to heap-based buffer
    overflows (CVE-2007-5392, CVE-2007-5393). He also discovered a boundary
    checking error in the DCTStream::readProgressiveDataUnit() method
    causing memory corruption (CVE-2007-4352). Note: Gentoo's version of
    Xpdf is patched to use the Poppler library, so the update to Poppler
    will also fix Xpdf.

  <impact type="normal">
    <p>
    By enticing a user to view or process a specially crafted PDF file with
    KWord or KPDF or a Poppler-based program such as Gentoo's viewers Xpdf,
    ePDFView, and Evince or the CUPS printing system, a remote attacker
    could cause an overflow, potentially resulting in the execution of
    arbitrary code with the privileges of the user running the application.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
