An issue was discovered in ytnef before 1.9.1. This is related to a patch described as "9 of 9. Directory Traversal using the filename; SanitizeFilename function in settings.c."
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.
