+	<h1>Problem Description:</h1>
+	<p>An unchecked array reference in the VGA device emulation
+	code could potentially allow guests 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 are running on.</p>
+	<h1>Impact:</h1>
+	<p>For bhyve virtual machines with the "fbuf" framebuffer
+	device configured, if exploited, a malicious guest could
+	obtain full access to not just the host system, but to other
+	virtual machines running on the system.</p>
