Multiple directory traversal vulnerabilities in pax 1:20140703 allow remote attackers to write to arbitrary files via a (1) full pathname or (2) .. (dot dot) in an archive.
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.
