Adobe fixes seven critical vulnerabilities in Flash Player, the fifth security update so far in 2012. The company also released the “silent update” tool for OS X, and prepped Flash for the upcoming OS X 10.8, aka Mountain Lion. Adobe also released a sandboxed plug-in for Mozilla’s Firefox. The tool is identical to the Windows version, which Adobe launched in March, pings Adobe’s servers every hour until it gets a response from the company’s servers 24 hours later. The silent update tool is set to automatically install future updates in the background.”]
