  <background>
    <p>ImageMagick is a collection of tools and libraries for manipulating
      various image formats.
    </p>
  </background>
  <description>
    <p>Two vulnerabilities have been found in ImageMagick:</p>
    
    <ul>
      <li>Incorrect offset and count values in the ResolutionUnit tag in EXIF
        IFD could cause memory corruption (CVE-2012-0247).
      </li>
      <li>IOP tag offsets pointing to the beginning of an IFD could cause an
        infinite loop of ImageMagick parsing the IFD structure (CVE-2012-0248).
      </li>
    </ul>
  </description>
  <impact type="normal">
    <p>A remote attacker could entice a user to open a specially crafted image,
      possibly resulting in execution of arbitrary code or a Denial of Service
      condition.
    </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 "&gt;=media-gfx/imagemagick-6.7.5.3"
    </code>
