how NATRON makes it possible to repair
Don't know if Natron have a 2d stabilizer (I know how to do this in Blender), but Natron have 2D Motion Tracker so probably you can stabilize your footage in Natron, try some Blender Tutorials or Nuke for 2d stabilization.
Yes natrons Tracker node offers stabilize.
Natron does have a tracker. As a matter of fact it is the same tracker as Blender!
It can be used to stabilize footage.
For more info on how to use the tracker check out Omar Brown's ( @NatronNation1) very useful post, the Unofficial Instruction manual for tracking in Natron:
