The openTempFile function in goo/gfile.cc in Xpdf and Poppler 0.24.3 and earlier, when running on a system other than Unix, allows local users to overwrite arbitrary files via a symlink attack on temporary files with predictable names.
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.
