Is there a backdoor in Safari 6.1? (Version 6.1 (8537.59))

With all this NSA spying going around, pardon me if I'm a little paranoid. I'm a registered Apple developer and was encouraged to download Safari 6.1 for testing. Here's what I saw when I clicked on the Privacy pane in Safari's preferences. https://www.youtube.com/watch?v=Frz0M41Bhv4 If you pause the video at the 5 second mark, it shows a dialog that auto-dismisses. Something about a "PluginProcess.app" attempting to connect to Safari. A little sleuthing shows that this is located at the following path: /System/Library/StagedFrameworks/Safari/WebKit2.framework/PluginProcess.app/Contents/MacOS/PluginProcess If I change the permissions to non-executable, the dialog goes away. I was hoping someone more technically-oriented could look into this.
