GHSA-F794-5JV7-7672 NLTK: Downloader.download follows hardlinks and overwrites outside-root files

Summary NLTK's downloader now blocks symlink escapes during ZIP extraction, but it still treats pre-existing hardlinks inside the install tree as ordinary in-root files. A normal package install can therefore overwrite an outside-root inode through that hardlink. Details - Vulnerability type:...
