os: avoid escape from Root via paths ending in ../

2025-05-06T18:33:18Z

The doInRoot function operates on a path split into components. The final path component retained any trailing path separator characters, to permit operations in a Root to retain the trailing-separator behavior of non-Root operations. However, doInRoot failed to take trailing separators into account when checking for .. path components. This could permit opening the parent directory of the Root with a path ending in "../". Change the split path to never include path separators in components, and handle trailing separators independently of the split path. Thanks to Dan Sebastian Thrane of SDU eScience Center for reporting this issue.
