ArcGIS Server and Portal for ArcGIS have already been upgraded to prevent issues due to the POODLE attack. The python libraries included in PortalPy include individual affected http modules. All micro releases of python (e.g. 2.7.8, 2.7.9) in a minor release line will be binary compatible and will just work if swapped in.
