iOS 4.0.2, 3.2.2 Updates Slay JailbreakMe Flaw
Got an iPhone or iPad? Be sure to update to iOS 4.0.2 for iPhone and iOS 3.2.2 for iPad. The two updates fix the nasty security flaw that made the widely publicized JailbreakMe hack possible.
The JailbreakMe exploit was, well, nasty. It made use of an apparent flaw in how iOS handles PDF documents (this bug shouldn’t affect other PDF readers, just the iOS one, according to Sophos).
Security expert Charlie miller characterized the JailbreakMe exploit as “very beautiful work,” and said that it’s ” scary how it totally defeats apple’s [sic] security architecture.” So while jailbreakers might be disappointed to see this hack go away, for everyone else it’s probably for the best. I mean, if a security bug can jailbreak your phone, there’s no telling what else it could do.
