rpcsvc: Validate RPC procedure number before fetch
While accessing the procedures of given RPC program in,
rpcsvc_get_program_vector_sizer(), It was not checking boundary
conditions which would cause buffer overflow and subsequently SEGV.
Make sure rpcsvc_actor_t arrays have numactors number of actors.
FIX:
Validate the RPC procedure number before fetching the actor.
