The sort_offline function for texindex in texinfo 4.8 and earlier 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.
