pdfjam creates the (1) pdf90, (2) pdfjoin, and (3) pdfnup files with a predictable name, which allows local users to overwrite arbitrary files via a symlink attack.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
