    <p>
    Tavis Ormandy of the Google Security Team discovered a heap-based
    overflow vulnerability in the NE2000 driver (CVE-2007-2893). He also
    discovered a divide-by-zero error in the emulated floppy disk
    controller (CVE-2007-2894).
    </p>
  </description>
  <impact type="high">
    <p>
    A local attacker in the guest operating system could exploit these
    issues to execute code outside of the virtual machine, or cause Bochs
    to crash.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Bochs users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-emulation/bochs-2.3"</code>
  </resolution>
