I'm working on a iMac 12.1 and i'm really happy to have my favourite Snow Leopard 10.6.8 OS, althought there are several problems with Adobe Flash Player. My internet browsers (Safari, Firefox, Chrome - tried everyone) can't show a frame with streamed video. Strictly speaking, Adobe Flash is the authoring environment and Flash Player is the virtual machine used to run the Flash files, but in colloquial language these have become mixed: Flash can mean either the authoring environment, the player, or the application files. For OS X 10.5 and later— Snow Leopard, Mountain Lion, Mavericks, or Yosemite— download and run this uninstaller. For OS X 10.4 and 10.5— Tiger or Leopard— download and run this uninstaller.
Two bugs, one affecting Apple's Mac platform and another attacking Microsoft's Windows, exploit certain Flash player vulnerabilities to install malware onto users' systems, reports ArsTechnica. While users of other operating systems like Linux have yet to report attacks, Adobe's advisory notes the exploit affects all platforms.
Designated as CVE-2013-0634, the first vulnerability targets the Safari and Firefox Web browsers running on OS X, and is also being used as a trojan to deploy Microsoft Word documents containing malware. For Mac users, the flaw affects Adobe Flash Player version 11.5.502.146 or earlier.
On March 1, 2013 Apple again blocked Flash Player for Lion and Mountain Lion:
The Adobe Flash patch can be found on Adobe’s website, and users can visit this page to check if their software is the most curent version.
