+	<h1>Problem Description:</h1>
+	<p>To implement one particular ioctl, the Linux emulation
+	code used a special interface present in the cd(4) driver
+	which allows it to copy subchannel information directly to
+	a kernel address. This interface was erroneously made
+	accessible to userland, allowing users with read access to
+	a cd(4) device to arbitrarily overwrite kernel memory when
+	some media is present in the device.</p>
+	<h1>Impact:</h1>
+	<p>A user in the operator group can make use of this interface
+	to gain root privileges on a system with a cd(4) device
+	when some media is present in the device.</p>
