  <synopsis>
    PDFlib is vulnerable to multiple overflows, which can potentially lead to
    the execution of arbitrary code.

    <p>
    PDFlib is a library providing functions to handle PDF files. It
    includes a modified TIFF library used to process TIFF images.
    </p>
  </background>
  <description>
    <p>
    The TIFF library is subject to several known vulnerabilities (see
    GLSA 200410-11). Most of these overflows also apply to PDFlib.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user or web application to
    process a carefully crafted PDF file or TIFF image using a
    PDFlib-powered program. This can potentially lead to the execution of
    arbitrary code with the rights of the program processing the file.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All PDFlib users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=media-libs/pdflib-5.0.4_p1&quot;</code>
  </resolution>
