helpvulnerabilityfixer for Mac

From Sample the Web:

I whipped up a small Apple Script app for myself, that simply turns on and off the preference within Help Viewer that allows it to automatically launch external scripts and which has been causing such a fuss as being a gaping security hole in OS X (even though I don't know of any real world exploits of this vulnerability that are in existence). In any case, all the scripts do is take the following command line code and wrap it in a script: sudo defaults write '/System/Library/CoreServices/Help Viewer.app/Contents/Info' NSAppleScriptEnabled -bool 'no'
Choosing OFF runs the above command, whereas choosing ON runs the same command with 'yes' substituted for 'no.' Boringly simple. Got the info from MacFixIt.
