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).

<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.

</impact>
|
|
<workaround>
