RECOMENDATIONS:

We recommend the following actions be taken:

Install the updates provided by Adobe immediately after appropriate testing.
Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
Remind users not to visit un-trusted websites or follow links provided by unknown or un-trusted sources.
Inform and educate users regarding the threats posed by hypertext links contained in emails or attachments, especially those from un-trusted sources.
