pscal in xcal 4.1 allows local users to overwrite arbitrary files via a symlink attack on a /tmp/pscal##### 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.
