    More-over the pilots will feel pretty obligated to go wherever the gun toting whack job threatening to shoot the other crew or passengers wants to go.

    Yep, you could hijack the plane for transportation, just like used to happen frequently in the 70s. Of course, just as then, the plane doesn't have enough fuel on board to get anywhere further away than its original destination, and you also have to figure out what to do when you land. See history for the ways that can go wrong.

    Hijacking to acquire a bunch of hostages you can threaten if authorities don't release your compatriots from prison proved to be similarly ineffective.

    But... it's actually worse now. Much worse. Because of 9/11, you may find it difficult to convince people that you're not planning to try to use the airplane as a missile. If you can't convince the passengers, they may well rush you and kill you, figuring they have nothing to lose. This has happened a few times, post-9/11, not to mention on Flight 93. And even if you can convince the passengers, you may not be able to convince the fighter jets who will shortly be trailing you.

    All in all, hijacking is a bad idea.

    what if the manufacturers have disabled SELinux or set it to be permissive?

    Then those manufacturers' devices cannot pass the Android Compliance Test Suite, and they have no right to call their devices Android and cannot use Google's apps. SELinux, in enforcing mode and with the Google-defined configuration (mostly; OEMs can make tweaks in some areas, but not the ones relevant to this vulnerability) has been a formal Android compliance requirement since Lollipop.

    It's a matter of time before a worm like Blaster hits Android and does some serious damage.

    I doubt it. Android is vastly more secure than Windows was (or even is... and Windows is much better than it was when Blaster hit). The lack of updates delivered by OEMs has caused the Android security team to focus on defense in depth, and the system is working pretty well (see last year's report -- or wait a bit for the new report which should be out in a few weeks). In particular, less than 0.1% of Android devices that use the Play store have any potentially harmful apps (PHA) installed, and that PHA definition is much broader than just traditional malware. Of the PHA apps, only about 5% try to exploit vulnerabilities; the rest focus on social-engineering the users.

    So, 0.005% of Android devices have some exploit-using malware on them. And AFAIK there are no Android worms. So, I really, really doubt Android is ripe for a Blaster.

    Fix your damn security model!

    The Android security model is actually very good... with one glaring exception, which is the update problem. But Google has committed to a monthly patch cycle for Nexus devices, and several other OEMs have hopped on that patch train. Thanks to that, carriers are being forced to get updated software through QA faster, and the focus on monthly updates is pushing OEMs to simplify their offerings to make updating them more practical (you probably won't see a visible reduction in number of offerings; but in the future I expect each model will have a handful of SKUs, at most, rather than hundreds as is often the case today).

    The update problem isn't going to get fixed overnight, but I think it is getting fixed, at least from top manufacturers. The next step is for consumers to insist on well-defined and sufficiently-lengthy support and update policies as a condition of purchase, to force all of the rest to get with the program.

    In the short term, if you want the most secure and up-to-date Android device, buy Nexus, but I expect soon others will be challenging Google for that spot.

    I see some slight evidence of increase in people making efforts to avoid advertisements, but it's small.

    Nonsense. People pay for Netflix for the convenience. Not having ads is a nice additional benefit, but not the primary goal.

    If Netflix were to put ads in shit, they'd be in serious trouble, and they know it.

    Yeah, I remember exactly the same claims during the rise of cable television, that cable providers who showed ads would die in short order. Notice what happened.

    Google will have a harder time. They have nothing of value that could fund their operations beyond the ad/tracking services. A crash in the ad market would probably be the end for Google.

    The Google Apps SaaS business could fund itself, including its supporting systems -- Gmail, Drive and Docs, primarily. It's already a multi-billion dollar business. Google Apps could also begin charging individual users. If advertising disappeared, so would all of the free e-mail services, so I think Gmail could begin charging and would keep most of its active users (though the large number of mostly-idle accounts would be shut down).

    Android could self-fund from the Play store now, and could probably get OEMs to start paying it for ongoing development.

    Google search, Analytics, Compute Engine and AppEngine are a question mark. It would depend on how much of the web died. If the web stayed healthy, then people would be willing to pay for search services, and webmasters would be willing to pay for analytics and compute services. But the loss of advertising revenue would likely destroy so much of the web that maybe there wouldn't be enough left to support these services. On the gripping hand, in that sort of webpocalypse, Google would be extraordinarily well-positioned to sweep up what business of that sort is available, so odds are that Google's would survive (much reduced), while smaller players would be driven out.

    The self-driving car work will be profitable. It's not ready yet, but not too far off and Google has the cash reserves to get it there.

    Other GoogleX work would probably die.

    So... Google would take a serious hit, have to scale back its operations in lots of ways and would have to start charging for many services which are currently free. I think all in all, though, it would have a much easier time surviving than Facebook, because Google's underlying services are more valuable.

    I hear you, but luckily it's not that bad yet. Back in 2011 some protesters were arrested and charged with failure to obey a lawful order. They were told to "move along" and failed to comply because they'd handcuffed themselves to the fence and couldn't. That arrest and charge had been the practice for decades, but in 2011 the government took the new step of prosecuting. Prior to that, protestors were always offered the option of posting $500 bail and forfeiting it rather than going to trial. If they did that, the charge would be dropped. In 2011 they weren't offered that chance, and were prosecuted. Most took a deal where they plead guilty but their charges were dismissed. One refused and went to trial. The story was complicated, but ultimately a misdemeanor conviction and $100 fine resulted.

    AFAICT, after that incident the government went back to the $500 get-out-of-jail approach.

    So, no, you can still shout in front of the White House. If you stand there and the police ask you to move along and you don't obey, it'll cost you $500.

    SELinux doesn't block access to this vulnerability, it merely makes exploitation more complex.

    In Lollipop SELinux it does make it impossible. Nothing in the system used these syscalls, so access to them is completely disabled by SELinux. If you can obtain root you can disable SELinux, but if you can obtain root you don't need the vulnerability.

    In Marshmallow there might be some possibility. A couple of system services started using the feature, so the SELinux configuration was partially opened up. We'll see if it turns out that there is some way to exploit it in Marshmallow. I suspect not, but if there is Marshmallow devices are also quite likely to be getting security updates, so most -- if not all -- will be patched very soon.

    KitKat is the vulnerable population. The portion of it that is using 3.10. After digging a bit more, I found that the Nexus KitKat devices were still on 3.4, and that was the configuration Google recommended. Some OEMs switched to 3.10, though.

    How are all of these Android versions in the wild going to get fixed?

    Since the bug didn't appear until kernel version 3.8, Jellybean devices are safe because Jellybean has kernel 3.4.39.

    Also, since Lollipop and Marshmallow have SELinux in enforcing mode, blocking access to the relevant syscalls, the bug is present but not exploitable on Lollipop and Marshmallow devices.

    This means that only KitKat devices (kernel 3.10) both have the bug and don't have SELinux blocking access to it. KitKat currently has about 36% market share.

    Incidentally, this also means that no Nexus devices are vulnerable. All devices newer than Galaxy Nexus have been upgraded to at least Lollipop, and so have SELinux protection. The GNex stopped at Jelly Bean, so doesn't have a vulnerable kernel (though there are other JB vulns).

    The better solution is just to abolish corporate income taxes. Corporate taxes ultimately come out of the pockets of real people anyway, whether customers (in the form of higher prices), employees (in the form of lower wages) or investors (in the form of lower gains), so corporate taxes are really just a way to tax real people (AKA "voters") in a hidden way. They don't know they're paying those taxes or how much the taxes are because the taxes are washed through the corporation -- which incidentally makes it almost impossible to tell if the taxes are progressive or regressive. This makes corporate taxes not only difficult to collect correctly and subject to huge lobbying pressure, it makes them evil. Taxes are fine, but taxpayers should know what they're paying.

    So the best solution is to eliminate the corporate taxes entirely, and make up the shortfall by taxing real people more. Depending on which segment of the population you want to be paying those taxes, you can allocate them among sales/VAT taxes, personal income taxes or capital gains taxes.

    It would also eliminates this particular competitive advantage of size.
