+ <h1>Problem Description:</h1>
+ <p>The bounds checking of accesses to guest memory greater
+ than 4GB by device emulations is subject to integer
+ overflow.</p>
+ <h1>Impact:</h1>
+ <p>For a bhyve virtual machine with more than 3GB of guest
+ memory configured, a malicious guest could craft device
+ descriptors that could give it access to the heap of the
+ bhyve process. Since the bhyve process is running as root,
+ this may allow guests to obtain full control of the hosts
+ they're running on.</p>
