To what does "zero day" refer?


Does "zero-day" or "0-day" (in context of software vulnerabilities and exploits) refer to the software release, or a particular type of exploit?

[I did not find an answer to this on SO. Though it is answered elsewhere on the Internet, my understanding of SO is that it's okay to ask/answer basic questions]


Solution

  • Simply put it means that it [the exploit] was released before the company was notified, and had the opportunity to fix it, because the company had 0-days of notification.
