shellshock vulnerability in android

shellshock vulnerability
shellshock vulnerability , executing commands after environment

 

I’ll try to put it as simple as possible to the readers from non information security background, ‘bash shell’ an inevitable part of unix based systems like Unix, Linux, Mac OS  is messed up badly by a easy to exploit  vulnerability that all hell broke loose. Shellshock aka Bashdoor  as it’s fondly called is a series of dangerous security bugs on the bash shell.

CVE-2014-6271

The first of these series, which would let anyone execute arbitrary commands following a crafted environment variable like this,

env x='() { :;}; echo vulnerable' bash -c "echo this is a test"

Speaking more on the vulnerability and it’s implications is beyond the scope of this article. Incase you are a power reader and wish to know in-depth regarding the vulnerability, please take a look at the excellent coverage on the same by troy hunt here.

What I really wanted to speak about here is shellshock’s implications in Android operating system.

Google, yesterday at a event in Mumbai announced new range of smartphones under ‘Android One’ banner which enables domestic handset vendors sell hardwares using google reference design and regular operating system updates from Google directly like it’s nexus line of smartphones but with one key difference – price.

Since Android One programme is aimed at countries like India, Philippines, Bangladesh  where smartphone penetration though growing at a massive rate still distributed lesser than feature phones, they are priced very competitvely.

The first set of Android phones announced here were  Spice Dream Uno, Karbonn Sparkle V and Micromax’s Canvas A1 priced INR 6,299, 6,399 and 6,499 respectively which is close to US $ 100. Since they all share the same reference design by google, they all share same hardware except for some customisations in enclosures.

Travelling Sales Person Problem how Quantum computer does it better
D-wave system

I checked out a recent article in BBC on Nasa/Google inducting a new Quantum computer – D-wave Two , what impressed me more was it’s benchmark results based on Travelling Salesman Problem(TSP). It’s been long, I did a math post so thought why not do small, simple demo on TSP for you and explain how Quantum computer like D-wave excels at it.

 

This demo is for people for whom combinatorial optimisation is new or those who want to check out implementation of TSP on Wolfram alpha. This post is not Computation/Mathematics experts as I won’t be covering any algorithms or optimisation approach, this post is just aimed at giving basic understanding of TSP.
