    <p>
    SEC Consult has discovered a buffer overflow in the code
    processing style sheet attributes. It is caused by an integer
    signedness error in a length check followed by a call to a string
    function. It seems to be hard to exploit this buffer overflow to
    execute arbitrary code because of the very large amount memory that has
    to be copied.

  <impact type="normal">
    <p>
    A remote attacker can entice a user to visit a web page containing
    a specially crafted style sheet attribute that will crash the user's
    browser and maybe lead to the execution of arbitrary code.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Opera users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=www-client/opera-8.54"</code>
  </resolution>
