A malicious or compromised SCP server could return file or directory names containing
path separators, drive qualifiers, or parent-directory references.
ScpClient.Download(string, DirectoryInfo) combined these into a local path without
validation, allowing writes outside the destination directory. Server-supplied C and D
record names are now validated before being combined into a local path.
