    Xavier Roche discovered an infinite loop in the gdPngReadData()
    function when processing a truncated PNG file (CVE-2007-2756). An
    integer overflow has been discovered in the gdImageCreateTrueColor()
    function (CVE-2007-3472). An error has been discovered in the function
    gdImageCreateXbm() function (CVE-2007-3473). Unspecified
    vulnerabilities have been discovered in the GIF reader (CVE-2007-3474).
    An error has been discovered when processing a GIF image that has no
    global color map (CVE-2007-3475). An array index error has been
    discovered in the file gd_gif_in.c when processing images with an
    invalid color index (CVE-2007-3476). An error has been discovered in
    the imagearc() and imagefilledarc() functions when processing overly
    large angle values (CVE-2007-3477). A race condition has been
    discovered in the gdImageStringFTEx() function (CVE-2007-3478).
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could exploit one of these vulnerabilities to cause a
    Denial of Service or possibly execute arbitrary code with the
    privileges of the user running GD.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All GD users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=media-libs/gd-2.0.35"</code>
  </resolution>
