Viewfile macros do not respect page restrictions

• Add a page
• Set viewing restrictions to user1 only
• Add an attachment - 'Sample.doc'
• Log in as user2 - confirm that you cannot see the restricted page
• Add a page, and use the viewfile macro
• Enter the location of the attachment on the restricted page

The contents of the attachment can now be viewed by user2. This is a serious violation of page permissions.
