Any reason for this high rating? Usually exploitation of these types of bugs require some sort of social engineering to convince the user to open the document which means that the exploitability will be lowered somewhat. This is because a bug that is noninteractive and can be exploited even against a user actively looking out for suspicious activity will be more readily exploitable vs something like this that could be caught and prevented by a vigilant user not opening suspicious attachments.
