Adobe has pointed in its security blog about a critical vulnerability in Flash Player. It is in all versions of Flash Player 12.0.0.43 to 11.2.202.335 for Windows and OS X and Linux hence all users are at risk using the software without updating.
Since the flaw allows hackers to take the control of the operating system remotely hence the users should update the flash player immediately with the emergency update released by the Adobe to close the gap.
Microsoft and Apple customers need to go for the Flash Player 12.0.0.44, users of Linux has to go for the patch 11.2.202.336. You can download it at the following link:
