CVE-2016-4171 is the fourth Adobe zero-day Flash update in four months. It’s a security exploit that comes out before any updates were available. But some zero days, being new and not very well tested, dont work reliably on all computers. Not all zero days are immediately widely available in the cybercriminal underground, because the crooks who figured them out want to keep them to themselves for a while. With that in mind, make sure youve received Adobes latest patch for Flash.”]
