  <description>
    <p>
    Alin Rad Pop from Secunia Research reported an integer overflow when
    processing CAF description chunks, leading to a heap-based buffer
    overflow.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to open a specially crafted CAF
    file, resulting in the remote execution of arbitrary code with the
    privileges of the user running the application.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All libsndfile users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=media-libs/libsndfile-1.0.19&quot;</code>
  </resolution>
