unrar 0.0.1 (aka unrar-free or unrar-gpl) suffers from a directory traversal vulnerability for RAR v2 archives: pathnames of the form ../[filename] are unpacked into the upper directory.
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.
