GNU Parallel before 20150522 (Nepal), when using (1) –cat or (2) –fifo with –sshlogin, allows local users to write to arbitrary files via a symlink attack on a temporary file.
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.
