Kindle Fire and Nook Upgrades Kill Root Access 275

jfruhlinger writes "The Kindle Fire and Barnes and Noble Nook tablets are similar enough and close enough together in price that they ought to be fighting market share and one-upping each other in terms of features they offer users. But the latest OS upgrades to both gadgets claims to be an 'upgrade' while actually taking functionality away: both remove the ability to root the device." A more balanced way of looking at it is that the updates fix known local privilege escalation vulnerabilities. This might be more of an issue for people wanting to hack on the Nook Tablet: its bootloader is confirmed locked, but reports lean toward the Kindle Fire having an unlocked bootloader letting anyone flash their own software without needing to gain root first.

        Actually, a privilege escalation exploit IS a security risk.

        The unlocked bootloader means that on the Fire, this is at most a small speedbump in the process of modifying a device. However this prevents malware from gaining privilege escalation. (Most of the easiest Android rooting techniques like psneuter and rageagainstthecage relied on exploits that could and WERE also used by malware such as Droid Dream.)

        It is. Most cars have the hood release inside the (presumably) locked cabin... and are hooked up to an alarm system.

        I agree with your sentiment; I just could not resist shooting at your analogy!

        • But in this analogy, you'd be allowed inside the cabin because it's the expected and normal usage of the car - you don't generally change/upgrade things from within the cabin beyond those the manufacturer/dealer approves (IE: swapping out a radio is pretty simple on most cars and doesn't usually void warranties). To "lock the cabin" of a tablet would be like the update changing the password/PIN and not letting the user in at all.

      Yeah, seriously. When you have a security flaw that allows root privilege escalation you don't just decide not to fix that because the homebrewer's were using it as a convenient way to get access to the machine. If this was on an (open) desktop platform, such a flaw wouldn't really be tolerated for long.

      It's like when people are upset that an exploit in a game was fixed that people were using to win / get free stuf / etc, yet they don't get upset when a bug is fixed that was actually preventing them from completing a game.

        Which is why the user should simply be given root access to begin with. Instead of having to use privilege escalation attacks, users should just be able to hit a button or flip a switch to enable root access for themselves. Quick, easy, and perhaps voiding the warranty (but I think anyone who wants root access is willing to have no warranty).

      This does not impact the Nook Color in any significant way.

      Both the Nook Color and Nook Tablet will try to boot off microSD first if they can. That's not part of the OS. However, the Nook Tablet requires a signed kernel to boot, and the Nook Color does not. So, this change results in a significant loss of hackability for the Nook Tablet, since you had to "jailbreak" it in some sense to do anything. It does not result in a significant loss of hackability for the older Nook Color, since you can still just write an unsigned kernel to a microSD card and you're off and running.

      Disclaimer: this is my understanding from scouring the xda-dev forums for details and from hacking my own Nook Color. I've confirmed that 1.4.1 on the Nook Color does close the sideloading "hole", and that a 1.4.1 Nook Color will still boot stuff like CM7.1 from microSD card. The rest of it, I have not personally verified myself, but am summarizing my understanding from reading experts talking about it all.

      The proper way to fix this isn't to block all rooting but to provide a working recovery means to reset the operating system to factory state, restore applications from the market, and restore the user's data from automatic backup. Then figure out a way to segregate the user's data so that it doesn't have to be restored as often; the "/sdcard" partition in some Android devices has worked well for this.

      That I eliminate a potential attack vector for malware

      You can't neutralize malware without first defining malware. This involves enumerating the possible bad things that malicious software can do. Does this list of bad things [laptop.org] miss anything?

        If you want to start a company to create a hobbyist tablet that is safe for rooting and experimentation, you should go ahead. But don't expect Amazon (or B&N) to sell a tablet designed to sell their own content while at the same time supporting your desire to run a different operating system on it.

        They are selling it at close to the manufacturing cost (or possibly below cost) because they are counting on it to bring in revenue. B&N doesn't want you rooting it and installing the Kindle App, or vice-v

  • If you want an eInk reader, then fine get a dedicated eReader. Otherwise get an Adroid tablet, not an LCD eReader.

    A year ago, getting something that you could convert to a decent $250 Android tablet was a BFD. Today, not so much.

    There were all kinds of great Black Friday deals: Acer Iconia for $200 and so on. You can still get a Vizio 8 at Costco for $189, or a Lenovo Idiapad A1 at Amazon for $199.

    Get a real tablet and you are not vendor-locked. You can read any format you want, without excessive hacking. P

      I have no idea what the hell the point of 'color' ereaders are.

      It's like we live in a world where there are two kinds of vehicles. Everyone either drives a enclosed electric golf cart, which is a good pollution-less short-range cheap vehicle, or a gas-powered car, which is more expensive but has a 300 mile range and is much faster and can carry more.

      And then vendors inexplicably start selling cars as 'gas powered golf cars', in the golf cart market. They've crippled these cars so they only have a range of

    In-case anyone hasn't read the Richard Stallman story: http://www.gnu.org/philosophy/right-to-read.html [gnu.org]

    From the authors notes:

    One of the ideas in the story was not proposed in reality until 2002. This is the idea that the FBI and Microsoft will keep the root passwords for your personal computers, and not let you have them.

    The proponents of this scheme have given it names such as “trusted computing” and “Palladium”. We call it “treacherous computing” ...

    The 1997 prediction, proposed in 2002, is reality in 2011. The big surprise is that the implementation isn't a technical DRM/TC scheme, but a fundamental change in corporations retaining ownership and control of items after they've been sold. Who could have predicted that?

    • That would be prophetic... if it wasn't for the fact that DVD players at that time already had private keys kept away from their owners and that the current generation of games consoles at that time were also locked down.

      Trusted Computing? Despite people like him getting hysterical about it, it still remains a feature designed for businesses who can turn it on if they wish to have the added security it provides, not something ever designed for consumer use.

      Slow on one prediction, incorrect on another.

    There are a number of exposure vectors for stuff like this. Certainly the average user does not want something that they buy/download to gain additional privileges and do unexpected things. Anything that makes that less likely is going to be required.

    I believe these devices are WiFi only and do not have a great deal of radio power, but you can believe anything with a cell radio in it is going to be locked down as tightly as necessary to absolutely prevent changing radio parameters. The first hacker that gets into a cell radio and shows the world how they can disrupt cell communications in their corner of the world will prove the need for this kind of lockdown beyond any doubt. But I don't see how this would apply to these devices.

    Certainly both devices are sold either at a loss or at a very, very thin margin with the expectation that they will be used to buy stuff from the parent company and mostly the parent company. Overall, Amazon has been quite generous with the Kindle line - supporting the 3G wireless access for web browsing, email reading, etc. Yes, you can download non-Amazon books through the Amazon-supported wireless access. I suspect with the Fire the capabilities are there to access free and paid content outside of Amazon, but the Amazon stuff is easier to get to. I have no idea what sort of capabilities the Nook has, but I am guessing both have NetFlix access just as an example. So the devices aren't really "owned" by their parent but the expectation that there will be future profits affect the price of the devices. Similar devices are normally priced a bit higher - as much as 50%.

    I do not think the parent "subsidy" is the reason for the lockdown as to the average consumer they are no more locked down now than before. If you can still pay NetFlix and watch movies on the device, then it isn't locked to only Amazon or B&N content.

    I think the only explanation that is reasonable is the absolute very last thing they want is any sort of downloaded software making its way onto one of these devices and taking it over. Anything that prevents that or makes it less likely is going get pushed out to the user community. Anyone criticizing this doesn't understand the risks or the incredible backlash that would follow from an exploit on one of these devices.

    • Lockdown is fine, but when the lockdown puts the owner of the device in jail then it's crossing the line.

      Baseband radios tend to be locked down yes. But there's no need for the application processor environment (android, etc.) does not need to be locked down beyond necessary security features. Well, no need beyond pro-corporate BS and control.
