    Xpdf is a PDF file viewer that runs under the X Window System.
    Poppler is a PDF rendering library based on the Xpdf 3.0 code base.
    GPdf is a PDF file viewer for the GNOME 2 platform, also based on Xpdf.
    libextractor is a library which includes Xpdf code to extract arbitrary
    meta-data from files. pdftohtml is a utility to convert PDF files to
    HTML or XML formats that makes use of Xpdf code to decode PDF files.

  <description>
    <p>
    Chris Evans has reported some integer overflows in Xpdf when
    attempting to calculate buffer sizes for memory allocation, leading to
    a heap overflow and a potential infinite loop when handling malformed
    input files.
    </p>
  </description>
  <impact type="normal">
    <p>
    By sending a specially crafted PDF file to a victim, an 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.
    </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-3.01-r5"</code>
    <p>
    All Poppler users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-text/poppler-0.4.3-r4"</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-r3"</code>
    <p>
    All libextractor users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=media-libs/libextractor-0.5.9"</code>
    <p>
    All pdftohtml users should migrate to the latest stable version
    of Poppler.
