I received a notice of an update for this very kind of thing a few days ago. So, again?
Well Flash is kind of always being exploited.
Seriously though turn off Flash and get a free version of Malwarebytes Anti-Exploit; Flash is used less and less online these days anyway.
On a related not I can highly recommend all of the products Malwarebytes has to offer, been using them for years and the CEO even took the time to do an email interview with me for my high school senior research project on malware.
