    data format for the storage and manipulation of scalar and
    multidimensional data. It is developed by the NASA.

  <description>
    <p>
    Leon Juranic reported multiple heap-based buffer overflows for instance
    in the ReadAEDRList64(), SearchForRecord_r_64(), LastRecord64(), and
    CDFsel64() functions.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to open a specially crafted CDF
    file, possibly resulting in the execution of arbitrary code with the
    privileges of the user running the application, or a Denial of Service.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All CDF users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=sci-libs/cdf-3.3.0"</code>
  </resolution>
