I added a Security Considerations section to the eXIf proposal: Exif Security considerations It is proposed to add the following two clauses to Section 7 (Security Considerations) of the "Extensions to the PNG 1.2 Specification, Version 1.4.0" document: The eXIf chunk may contain data such as image resolution and dimensions that are redundant with existing PNG chunks. Applications must be prepared to handle such redundant and perhaps conflicting information. The eXIf chunk may contain a "thumbnail" or a "preview" of the image. If the image has been redacted or otherwise edited, authors may be surprised to learn that they have leaked private information by publishing an unredacted image.
