A bug in Microsoft’s Internet Explorer browser is causing more than 50
million files stored online to leak potentially sensitive information that could
compromise user privacy, a security researcher said.
The documents stored in Adobe’s PDF format display the internal disk location
where the file is stored, an oversight that can inadvertently expose real-world
names and login IDs of users, the operating system being used and other
information that is better kept private. The data can then be retrieved using
simple web searches.
