discovered a divide-by-zero error in the emulated floppy disk
controller (CVE-2007-2894).

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>
There is no known workaround at this time.

</workaround>
<resolution>
