Re: 0-day "vulnerability"

The term "0-day (or zero-day)" means the action has been done very quickly even without giving the developer enough 
time to fix the vulnerability of the software in question. Some commonly used terms are 0-day attack, 0-day exploit 
etc. So if you take that into context, the terms like "0-day vulnerability" or "0-day disclosure" are technically 
incorrect, IMHO. 

I would like to define it like this:

"0-day x" where not all x are 0-days.

Arguments welcome :-)

Yep. Totally agree. Vulnerability exists in the system since it has been developed. It is just the matter when it has 
been disclosed or being exploited. 

I would suggest " 0 day disclosure" instead of "0 day vulnerability" :)

Sorry to rant, but I have seen this term used once too many times to
sit idly by. And used today by what I once thought was a respectable
infosec publication (that will remain nameless) while referring to the
current Firefox vulnerability (that did, by the way, once have a 0-day
sploit)  Also, by definition, a 0-day no longer exists the moment it
is announced ;)

For once and for all: There is no such thing as a "zero-day
vulnerability" (quoted), only a 0-day exploit...
