The (1) tramp-make-temp-file and (2) tramp-make-tramp-temp-file functions in Tramp 2.1.10 extension for Emacs, and possibly earlier 2.1.x versions, allows local users to overwrite arbitrary files via a symlink attack on temporary files.
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.
