Talk:Incomplete Codesign Exploit

This has to be one of the most puzzling exploits in iOS. Since it was revealed in 3.1.3/3.2, Apple has yet to close it in 4.0, 4.02, or 4.1 or even 4.2 betas.

Somehow, once you stick a dynamic library or other goody with some sort of "incomplete codesign" magic in the right location and add a startup service, iOS will execute it. Perhaps Apple has no way to fix this without breaking other things? Iemit737 00:23, 10 October 2010 (UTC)

AFAIK IncompleteCodesignExploit is an exploit in WWDR Cert Checking that allows ppl to create fake entitlements. Obviously I'm not sure it works in this way. --Qwertyoruiop 00:41, 10 October 2010 (UTC)

Should we decribe it or is it better to wait until Apple fixes it? --Redart 07:44, 21 October 2010 (UTC)

i think it cannot be patched also the codesign need's to be patched to run jailbroken apps because codesign would kill any applications not signed by Apple --liamchat 17:56, 26 October 2010 (UTC)

It is patchable, all kernel based exploits are since it is software based. --JakeAnthraX 18:00, 26 October 2010 (UTC)

then why has apple not patched it because it will make all app's in the app store need updating ( to use a unique key with the Codesign ) --liamchat 18:18, 26 October 2010 (UTC)

Weather or not Apple decides to patch it, doesn't mean it is unpatchable. Just that they are having problems doing it. --JakeAnthraX 18:26, 26 October 2010 (UTC)

i just noticed something looking at the CodeResources in the _Codesign folder and look at an app from an ipsw [1] and an appstore app [2] both sandbox and this where introduced in firmware 2.x --liamchat 18:44, 26 October 2010 (UTC)
