Attention all you jailbreakers! The iPhone jailbreak available through Jailbreakme.com, accesses a jailbreak through a gaping PDF security hole Apple left. Which means that until iOS4.1 arrives, that security hole is still there, for all iPhones. If you did jailbreak though, Cydia has a solution.
The hole that the jailbreak uses is in the safari browser, allowing PDF downloads to access the root file system of the iPhones running iOS 4.0 and iOS 4.0.1. One way of avoiding the now very well publicised hole is to get PDF Loader Warning from Cydia, which notifies you every time you’re going to open a PDF.
PDF Loader Warning carries no icon, and is free from BigBoss through Cydia. There’s reports of a minor glitch with the Cydia app though, namely that it can get stuck in a short notification loop when viewing the clock. We found that six clicks was enough to clear it.
Apart from this though, it’s a good way to add an extra level of security to your jailbroken iPhone, as many commenters on forums are pointing out, Jailbreakme.com highlighted a major hole in iPhone security, and whilst it allowed for a jailbreak, it also points out the flaw to evil hackers.
Will you get the app with you iPhone jailbreak, or are you waiting for a proper security patch?
