no need for CV. Unless the person mentioned "refer to my attached CV" in the letter, in which case you should only provide the front page and leave a mark somewhere in the index that "only the front page has been shown, the full CV can be provided upon request."
when u ask for the reference's cv, u should say a one-page brief version cv. now u already got the cv. u can either drop it or revise it and send the revision to the guy and explain the situation too see whether he has any comments.
