Adobe has published an emergency Flash update to protect against a zero day exploit. A second zero-day, called CVE-2015-0311, was mentioned by Adobe in a separate advisory, but no patch is yet available. Even if you are unpatched, good defence-in-depth malware prevention can stop you getting infected. Even though you apply a patch, the same crooks may have other ways to infect you. The Angler exploit kit is reportedly being used to carry out zero-days attacks using the exploit.”]
