    <p>
    Christoph Deal discovered that JPEG files with a specially crafted DHT
    marker can be exploited to cause a heap overflow. Furthermore, an
    anonymous person discovered that Opera does not correctly handle
    objects passed to the "createSVGTransformFromMatrix()" function.

  </description>
  <impact type="normal">
    <p>
    An attacker could potentially exploit the vulnerabilities to execute
    arbitrary code with the privileges of the user running Opera by
    enticing a victim to open a specially crafted JPEG file or a website
    containing malicious JavaScript code.
    </p>
  </impact>
  <workaround>
    <p>
    The vendor recommends disabling JavaScript to avoid the
    "createSVGTransformFromMatrix" vulnerability. There is no known
    workaround for the other vulnerability.
    </p>
  </workaround>
  <resolution>
    <p>
    All Opera users should update to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=www-client/opera-9.10&quot;</code>
  </resolution>
