    <p>
    Andrei Nigmatulin discovered that a Photoshop Document (PSD) file
    with more than 24 layers could trigger a heap overflow.
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could potentially design a mailicous PSD image file to
    cause arbitrary code execution with the permissions of the user running
    ImageMagick.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All ImageMagick users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=media-gfx/imagemagick-6.1.8.8&quot;</code>
  </resolution>
