Vulnerability discussion

PowerPoint presentations that are saved in standard or HTML format can contain a flag indicating whether markup (comments or ink annotations) in the presentation should be visible when the presentation is open. PowerPoint ignores this flag when opening a file, and always displays any markup present in the file. In addition, when saving a file, PowerPoint sets the flag to display markup when the presentation is next opened.If this default configuration is changed, PowerPoint sets the flag according to the state of the Show Markup option on the Review tab of the Ribbon when it saves presentations in standard or HTML format. In addition, PowerPoint enables or disables the Show Markup option according to the way the flag is set when it opens files, which means that a presentation saved with hidden markup is opened with the markup still hidden.If a file is saved with hidden markup, users might inadvertently distribute sensitive comments or information to others via the presentation file.

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.
