App Store Bug Corrupts Binaries; Angry Birds Crash 116

          I guess it would be easier to state that while application are packages, packages are not necessarily applications. So a package manager might be an application distribution system, but an application distribution system is not a package manager. In simpler terms - an application distribution system incorporates a very specific set of functionality, removing several aspects of a general package management system, including things like dependency hierarchies which can cause problems cross-applications, espec

      That's the weird thing, though... Apple not only DOES check it, they require the developer to cryptographically sign the entire package with keys they provide, and apps won't run unless it matches. There should be nothing in between that could modify code without tripping that up.

      • Huh, then you have to wonder whether the signature process failed or the hash process failed...if the signature process failed and the App Store not only passed incorrectly signed apps onto devices but allowed them to be installed, that's a security vulnerability.

          I'd suspect something a bit more innoculous.- like data center storage corruption.

          iOS apps are encrypted - or rather, parts of them are. The executable has portions of its code and data segments encrypted, and the list of encrypted parts and the decryption key are then encrypted with the user's Apple ID key. That key is transferred to the device so that iOS can decrypt the binary encryptoin key and the list of encrypted segments (there aren't any headers).

          The reason apps can crash would include either the encryption table is blank and iOS decrypts the binary incorrectly (probable cause - disk full) thus causing corrupt code and data to be executed, or perhaps everything IS encrypted properly, but the binary is corrupt.

          The former would be erratic - some people would find it works correctly, others not, and it wouldn't matter if updates happened because it would occur on any download. The latter would mean the storage system has failed and thus during the DRM process, it's DRM'ing corrupt binaries.

          Since it's specific binaries that do this, perhaps some of Apple's massive storage servers have failed catastrophically. (they use iSilon/EMC storage servers at their NC datacenter I believe). And also why re-uploaded versions of same work - they were put on more stable storage.

          FYI - the way pirated apps work is they run the app, then use GDB to halt execution. Then they use GDB to dump the running image back out to get the decrypted version which then replaces the encrypted chunks with the decrypted versions.

          I would also guess that Apple's "fixing it" because I kept running into issues downloading ("This application is not currently available").

        If "they" in the first sentence is Apple rather than the developer (and its not clear what the referent fro that pronoun is), then Apple has the keys and could modify the package after it is provided by the developer. Why they would do so is unclear, but it would

      • by rabtech ( 223758 )

        Well if you RTFA, you will see that it is actually the decryption that fails. The package itself validates as being properly downloaded (the bits sent by the server are the bits received), but the binary is corrupt and not properly encrypted so the OS refuses to run it.

        The problem appears to be in the distribution system that signs the binary then distributes the package across the CDNs, after App Review approves it. The current theories are that the signing system is somehow incorrectly signing a mismatch

          IOW, TFS is simply wrong: the application isn't crashing. Everything is working exactly as it should, except for some intermediary storage in the App store.

    • by mellon ( 7048 )

      Yeah, I'm _really_ confused by this story. In order to publish an app, you have to sign it with your developer key, and Apple has to sign it too. How is it even _possible_ for a corrupted app to run on an iOS device? Wouldn't it just fail the signature check?

          Dealing with the end users properly should include a statement of the form such as "this is what went wrong, this is how we're fixing it." If it doesn't include information similar to that, the users are going to be just as dissatisfied as they were before, and maybe more so. That means asking the people fixing the problem "what went wrong? How soon can we fix it?"

    This happened to our product last week. The issue seemed to be that most users who tried to download the application were instead getting the old version (despite app store thinking the product was updated)... You could see this if you pulled the binary off the device and looked into the binary size / info.plist (all the information matched).

    There were 2 work arounds we discovered:

    1. Users could fix their individual application (If they're app is crashing immediately), by deleting the app, and redownloading it from iCloud (go into purchase history to find the application and download it from there, NOT the app front page).

    2. Apple worked for a while on our issue but didn't come up with a resolution, instead we were able to get it back into operation by "Hitting the reset button" -- First, remove the app from sale in the store (set the available regions to none), wait until that propagates (could take a few hours) then, put it back. This fixed our issue. Hopefully now that more people are reporting this issue Apple will actually take the time to fix it.
