You can either do fourth finger there, or play a normal D for the open e, f, g bit, then at the end of the g, reposition the finger for the fifth.

Quick update as well, don't know how you're bowing this, but my inclination would be :
upbow for the d, down for the e and f (slightly accelerating the f), separate bows for the two d's, then up for the g and two d's that follow (separating the d's with a cut on the fourth finger), down for the a, up for the d, bowed treble for the triplet slurring into the last note on the down, up for the d (to be slurred into the first beat of the next bar).
That seems to make the thing flow better for the fingered fifth.
