Directory traversal vulnerability in Subversion before 1.4.5, as used by TortoiseSVN before 1.4.5 and possibly other products, when run on Windows-based systems, allows remote authenticated users to overwrite and create arbitrary files via a ..\ (dot dot backslash) sequence in the filename, as stored in the file repository.
Improper Limitation of a Pathname to a Restricted 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.
