Paranoid Android can protect against a vulnerability in OS X involving the use of URL "schemes". It does this by watching the URL schemes that are requested and delaying them until you've had a chance to say whether you'd like to proceed or not. Paranoid Android can protect you from this potential vulnerability until Apple makes an official fix available.

A further vulnerability in the way Mac OS X handles strong document bindings can lead to documents opening in a different application when opening a document causes an application to launch. This can lead to an arbitrary execution of code. Paranoid Android has been updated to address this new vulnerability.

Paranoid Android can protect you from this potential vulnerability until Apple makes an official fix available. It does this by watching which applications a document will open in and if it isn't the default application for that file type, it will delay them until you've had a chance to say whether you'd like to proceed or not. If the application that will be launched is not the one you expected to be launched, Paranoid Android gives you an opportunity to open the document in the default application for the file type.
