    <p>
    Tielei Wang reported multiple integer overflows, possibly leading to
    heap-based buffer overflows in the (1) read_png_file() and
    read_png_file_as_rgb24() functions, when processing a PNG image
    (CVE-2009-2295) and (2) gifread.c and jpegread.c files when processing
    GIF or JPEG images (CVE-2009-2660).
    </p>
    <p>
    Other integer overflows were also found in tiffread.c (CVE-2009-3296).
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to open a specially crafted,
    overly large PNG, GIF, TIFF, or JPEG image using an application that
    uses the CamlImages library, 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 CamlImages users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose =dev-ml/camlimages-3.0.2</code>
