Absolute path traversal vulnerability in xftpd in the FTP Server component in Apple Mac OS X before 10.6.8 allows remote attackers to list arbitrary directories by using the root directory as the starting point of a recursive listing.
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.
