Quoting from 3.5.4 release notes:
"Several unlikely crashes found by fuzzing have been fixed."
@maintainer(s), please advise if ready for stabilisation, or call yourself.
Given that these crashes are unlikely, if you are not yet comfortable with stabilisation, there is no problem.
Why not go straight for 3.6.4?

Restarting stabilization with newer version due to bug 704894.
