Directory traversal vulnerability in the minitar before 0.6 and archive-tar-minitar 0.5.2 gems for Ruby allows remote attackers to write to arbitrary files via a .. (dot dot) in a TAR archive entry.
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.
