Path traversal via Clean on Windows in path/filepath

Quick fix

GO-2022-0533 — stdlib: upgrade to the fixed version with the command below.

go get stdlib@v1.17.11

Details

On Windows, the filepath.Clean function can convert certain invalid paths to valid, absolute paths, potentially allowing a directory traversal attack.

For example, Clean(".\c:") returns "c:".
