Vulnerability discussion

Acrobat provides the ability for the user to store a list of websites with an associated behavior of allow, ask, or block. Websites that are not in this list are unknown. PDF files can contain URLs that will initiate connections to unknown websites in order to share or get information. That access must be restricted.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
