Just a week after releasing its regular monthly security update, Adobe Systems has issued six new security patches. The fixes plug vulnerabilities in Flash Player. If left untreated, they could cause a system crash or allow attackers to take control of a computer.

SearchSecurity.com reported the new patches apply to Adobe Flash Player Version 11.3 and earlier. They must be applied to Flash running on Windows, Macintosh and Linux. Android smartphones are also affected.

Adobe gives the latest patches the highest priority rating for Windows computer users. That means you've got to install them as fast as possible, like by Friday.
