Adobe warns of Flash zero-day vulnerability

“As I write this, if you’re running Adobe Flash on your Windows, Mac, Linux or Chrome OS computer you’re potentially at risk,” remarked the independent security analyst Graham Cluley. The expert was commenting on Adobe’s latest security advisory, which stated that a vulnerability had been identified. Mr Cluley said: “Obviously it makes sense to run a layered defence on your computer systems, which includes keeping your antivirus and other software updated.”
