The Adobe Creative Suite 3 installer for Version Cue CS3 Server disables your Mac’s firewall so that it can configure new outgoing network ports, but it does not reactivate the firewall when it is finished — potentially leaving your Mac open to malicious attacks.

Version Cue CS3 Server is included with Adobe Creative Suite 3 Design Premium, Design Standard, Web Premium and Web Standard. It is installed by default as part of the full Creative Suite 3 installation.

To re-enable the Mac OS X built-in firewall, do this:

1. Choose Apple menu> System Preferences.
2. Click the Sharing Preference Pane.
3. Click the Firewall tab.
4. Click the Start button to turn your firewall on. (If the button says Stop, your firewall is already running.)

Enabling your Mac’s built-in firewall is an easy way to help prevent unauthorized people from accessing your computer through your local network or through the Internet. If you don’t already have your Mac’s firewall turned on, this is a great opportunity to activate it.

We don’t know if Adobe is planning to change the Creative Suite 3 installer, but they are offering the same advice we are: check your firewall settings yourself.
