To be honest, I am not even sure of the circumstances to which that vulnerability did exist, so I not really sure about the impact it had...
That said, the fact that an update was released for it, says that maybe it was an issue...
I am just a user like you, so I am not too sure about the reasoning behind the updates...I would say that *maybe* it is because some people may not like the fact that they have to download updates within a short time...but as said, I don't really know...
Unprotected?
Not sure, depends on the circumstances I suppose...
What I find funny though, is that when no-one knows about it, all is well...
They do say, ignorance is bliss...
Overall, I'd say this would be down to one of the ALWIL team to answer this properly, I was just suggesting a possible reason.
