An issue was discovered in GNOME file-roller before 3.29.91. It allows a single ./../ path traversal via a filename contained in a TAR archive, possibly overwriting a file during extraction.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
