The 26.9MB patch – named MS12-063 – provides a fix for the flaw, which is in use by hackers against some companies. It also features four more flaw-fixes, which as far as it is known have not been discovered by users, according to Microsoft.

"The majority of customers have automatic updates enabled and will not need to take any action because protections will be downloaded and installed automatically. For those manually updating, we encourage you to apply this update as quickly as possible," said a Microsoft spokesperson.

The flaw was rated as critical or moderate risk, depending on which browser and operating system you are running, but would allow full remote code execution on systems running IE 7,8 and 9 running Adobe Flash on fully-patched Windows XP, Vista and 7 machines, using malware embedded in a web page.
