This is a known limitation.  The workaround, per the Emacs manual and
the doc string of dired-listing-switches, is:

     Dired does not handle files that have names with embedded newline
  characters well.  If you have many such files, you may consider adding
  ‘-b’ to ‘dired-listing-switches’.  This will quote all special
  characters and allow Dired to handle them better.  (You can also use the
  ‘C-u C-x d’ command to add ‘-b’ temporarily.)

Unfortunately, we cannot add -b to the switches by default because it
is problematic with other nonprintable characters that Dired handles
well without -b.
