Critical Security Fixes for Adobe Flash Player
Summary: Adobe released Flash Player 11.3, which fixes at least seven security vulnerabilities in Flash Player and Adobe Air that attackers could use to crash the applications and seize control of unpatched systems. The release also extends the background updater to Mac OS X users browsing with Mozilla Firefox, checking for updates hourly until the Adobe server responds and then every 24 hours if none is available.
What you should know: Adobe warned that these flaws let attackers crash the applications and take control of unpatched systems, and the update covers Windows, Mac, Linux and Android - so any unpatched Flash install remains exposed until it is updated.
