+ <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>
