Narrative:

ATC warned us of VFR traffic at 17;000 ft. We picked him up on TCAS. We were on collision course with him and he passed us with only 300 ft vertical separation. We got a TCAS RA and were forced to take action to avoid a possible collision. We never saw him visually but TCAS indicated that he passed directly overhead with 200-300 ft separation. With a VFR pilot flying at 17;000 ft without communications with ATC; ATC could have been more urgent in its information about the traffic.
