    Exiv2 is a C++ library and set of tools for parsing, editing and saving
    Exif and IPTC metadata from images. Exif, the Exchangeable image file
    format, specifies the addition of metadata tags to JPEG, TIFF and RIFF
    files.

  <description>
    <p>
    Meder Kydyraliev (Google Security) discovered an integer overflow
    vulnerability in the JpegThumbnail::setDataArea() method leading to a
    heap-based buffer overflow.
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could entice the user of an application making use of Exiv2
    or an application included in Exiv2 to load an image file with
    specially crafted Exif tags, possibly 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 Exiv2 users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=media-gfx/exiv2-0.13-r1&quot;</code>
  </resolution>
