  <description>
    <p>
    iDefense Labs reported that the TIFF parsing code uses untrusted values
    to calculate buffer sizes, which can lead to an integer overflow
    resulting in heap-based buffer overflow.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to open a specially crafted
    document, possibly leading to execution of arbitrary code with the
    privileges of the user running OpenOffice.org.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All OpenOffice.org users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-office/openoffice-2.3.0"</code>
    <p>
    All OpenOffice.org binary users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-office/openoffice-bin-2.3.0"</code>
