Adobe has a  large release as part of their monthly security update process.  They usually release on the same day as Microsoft’s “Patch Tuesday”.  Users should patch expediently, as prompted.

If you still have Adobe Flash installed on your computer, you should patch it pronto – regardless of whether you are running Windows, OS X or Linux.   Yesterday, Adobe released a Godzilla-sized patch that fixes a sea of over 30 different security vulnerabilities in Flash and Adobe AIR.   If left unpatched, it’s possible that malicious hackers could exploit the vulnerabilities to infect your computer with malware. The good news is, so far at least, Adobe hasn’t seen any evidence of the vulnerabilities being exploited in the wild.  But don’t let that fool you into thinking that patching isn’t still a high priority.

The most recent version of Flash is always available from the Flash download page.
