Amen to this. My personal belief is that one can not say what is the
severity of a bug. It all depends on how the equipment is used. It
may not be much about if it is a large network or not but if that
feature is used. Another question is "What is worth of your data?".
If some bug will expose something that is public anyway then it
boils down a nuisance. If it will expose your confidential data then
it is very serious indeed. The vendor can not know how a particular
feature will be used in a customer's environment. Yes, a vendor may
have some idea but, is it valid in all cases?
