Sorry to disappoint, but those are not changes that make the system more
vulnerable.  They are externalities that may change the likelihood of 
exploitation of an existing vulnerability, but does not create any new 
vulnerability.  Again, if the new exploit were targeting a vulnerability
which was fully mitigated already and thus could not be exploited, there
has not even been a change in likelihood of exploit or risk.
