A new Adobe Flash vulnerability
This one affects everybody (yes, you too Linux) and looks pretty scary. It was found amongst the things leaked from the Hacking Team.
See [here](https://www.securityweek.com/adobe-patches-hacking-teams-flash-player-zero-day) for the story and [here](https://helpx.adobe.com/security/products/flash-player/apsa15-03.html) for the advisory from Adobe.
Edit: As someone noted, this has been patched in the latest version (as noted [here](https://helpx.adobe.com/security/products/flash-player/apsb15-16.html) with links to the updates released on July 8).
