Exploitable Backhole Accidentally Left In Some MediaTek-based Phones (ndtv.com)

Posted by timothy on Monday February 1, 2016 @03:13AM from the so-no-using-the-phone-ever dept.

Lirodon writes: MediaTek has confirmed findings by security researcher Justin Case, who discovered that some devices running Android KitKat on MediaTek processors (often used in lower-cost devices) had a debug function, meant to be removed on production devices, accidentally left in by their manufacturer. This hole could be used to trivially gain root access, among other possibilities.

  It's called a "backdoor" and here is a link to more information (the link posted in the summary has nothing to do with the backdoor):
  Probably whoever came up with "backhole" didn't want to use "backdoor" because they felt that, since doors aren't naturally occurring, describing this security vulnerability as a "door" means that it must have been put there intentionally. Whereas, in fact (as near as I can tell), this vulnerability is due to a software error, albeit seemingly an failure of release management rather than programming per se. Thus, "hole" instead of "door".
  That said, I'd like to leave our distinguished editor Timothy with this thought:

  Because they haven't progressed to contextual translation yet, which includes phrases and grammar structure translation.

  Because asian languages don't map well to English to begin with. Japanese at least uses far fewer words with very many potential meanings, and it's great for humans since we know the context. But if I told you to turn "cloud go here strength west", you'd struggle quite a bit to not add extra detail the author never said and still make a fluid sentence. Magnify by that a hundred fold because a machine doesn't even have basic intuition, and I'm actually suprised by how it sort results in somewhst readahle sentences, sometimes.
  That being said, I'm surprised by the poor quality of German. English and German are even in the same family linguistically speaking... Germany's not a very sexy language, but still, I'd have figured it might be an easy lower hanging fruit. I guess maybe we are at the limits technologically speaking then, here's hoping in 10 years we're further along.

  In some ways yes, but apparently in some ways no.
  Years ago a friend was taking German classes, and apparently it has subject/verb stuff which can be at the end of sentences.
  So one example of how it fell apart was a place in which the speaker went on for a long time, and the translator just stopped ... because without knowing what was at the end of the long-winded sentence it was impossible know what to say next. It was a lot of stuff which couldn't be translated into English until it was all done -- and it took a VERY long time for that speaker to be done.
  I got the impression that are still enough structural differences that it's more than a little challenging for skilled humans to do it.
  So, if translating in real time can be near impossible, then I assume it's still damned easy for static translations to get mired down into stuff it can't handle well.

  They might be in the same language family, but that is because they have the same primary root language. In the case of English, there was the initial celtic language, similar to Welsh, that would have had some parts assimilated into the versions of Saxon & Angle that merged into the pre-Norman tongue. Then there were the Normans, speaking French, a derivative of Latin with some input from ancient Gaulish, another celtic language. They also influenced the development of English, both it's lexicon and probably its grammar. It will also have been influenced by Irish, Scottish Gaelic, Welsh, Cornish, and even Indian. Languages don't just change in isolation, they also change with human migration and intermingling of cultures.

  One of the big challenges in translating from German is the prevalence of compound words whose meanings vary by context, and which often don't match the base words' definitions at all. We use our fair share of compound words in English, but their meanings are typically evident. For example combining "light," a source of brightness, plus "house," a domicile where you take shelter, gives us "lighthouse," a structure that protects a source of brightness. Makes sense, right? Most (obviously not all) English compound words can be easily reverse-engineered, so to speak.
  In German, you have many thousands of examples which aren't nearly so clear. Consider "Fingerspitzen," the tips of your fingers, plus "Gefuhl," feeling, which gives us "Fingerspitzengefuhl," an innate and heightened sense of situational awareness. This makes a bit of sense in an abstract way that a human can understand once it's explained: "fingertip feeling" is a short way to express "I can feel it in my fingertips," which can then be interpreted as "I'm completely in touch with my surroundings." It's currently very difficult for a machine to extract the meaning from the context from the metaphor from the compound word, though - and German is just full of these words.
