CVE: CVE-2011-3230 Found By: Aaron Sigel of vtty.com There's not a ton to say about this bug aside from "Yikes"! I think the PoC speaks for itself. This allows you to send any "file:" url to LaunchServices, which will run binaries, launch applications, or open content in the default application, all from a web page. The only caveat is that since LaunchServices will check for the quarantine bit, you cannot directly push a binary to the browser and launch it. Other than that, you can run or launch anything you can access by using the method in the html provided below.
