update sim card???
Is the article suggesting that my SIM card needs to get a software update? How? Or is everyone going to be
knocking on the door of their local phone shop? The mind boggles, as they say. I must have mis-read that. It's late.
Bug hunters say Oracle's Java Card platform is host to a dozen and a half security flaws that could place smart-cards and similar embedded devices using the tech at risk of hijacking. Adam Gowdiak, CEO of Security Explorations, said he and his team discovered and privately reported the vulnerabilities to Oracle and smart-card …
This is JavaCard, not Java - a very different beast. And you'd be hard-pressed to find a phone's Secure Element, or a SIM card, or a credit/debit card, that doesn't use it.
However, these security "revelations" are noteworthy for being far from original. It has always been understood that there is a gap between the off-card bytecode verifier and the on-card bytecode interpreter. That's why anyone implementing the JCVM pays a lot of attention to security considerations.
The Oracle reference implementation of v3.1 is an easy target - the clue is in the name, it is a reference implementation, functionally correct but without the hardening you need for a smartcard.
And the two Gemalto products they "cracked"? Technology over ten years old (3G? we've moved on a bit from that...).
It's like sending an email to Microsoft to tell them you've found a bug in Windows XP.
So no "security storm", no rushed patches from Oracle, no new flaws, and no need for any "fixes".
P.S. I'm not a Gemalto (or Gemplus) employee (or ex-employee).
Agreed. I have implemented many a class loader and this problem would have been caught by the byte-code verifier. We never thought it was a good idea to punt on the byte-code verifier but do remember that the earliest SIMS were very underpowered.
SIMs nowadays are more powerful and can use byte code verifiers and decent class loaders.
Take a CPU with Harvard architecture so it physically can't execute what ought to be data, manufacture it on a (by modern standards) huge process node so it's less prone to external interference from electromagnetic attacks and such, give it temperature and light sensors so it can tell if someone's trying to tamper with it other ways, design it with hardware-based isolation between processes including strongly-encrypted memory, provide it with a true hardware-based random number generator so encryption key sequences can't be predicted, and then put Java on it. It's like having the world's most secure bank vault but leaving the door unlocked. So yeah, 3 billion devices do run Java, but all of them are vulnerable.
Oh, and the applets are called cardlets if you're being fussy.
Never heard of a JavaCard "cardlet" (it's certainly not the English term), but I do know that each and every applet extends the javacard.framework.applet class... hence the name.
Again, it is not Java, it is JavaCard, and the VMs are constructed to cater for the vulnerabilities inherent in off-card verification and on-card execution. These smartcards undergo extensive evaluation before being allowed to host credit/debit applications.
This is money we are talking about - don't you think that Visa and MasterCard might have a vested interest in making the system a bit more secure than leaving the bank vault door unlocked?
Not Oracle. It was Sun and IBM - well it was 16 years ago.
It's worth noting this:
"It should be emphasized that successful loading of a malicious applet into target card requires either knowledge of the keys or existence of some other means facilitating it (a vulnerability in card OS, installed applications, exposed interfaces, etc.). Such scenarios cannot be excluded though."
Unless you're at the bureau producing the cards, then those private keys will be well hidden. The card manufacturer is on the back. My Mastercard is GemAlto.
Each app provider also has their own keys. Here's a list of the apps. https://www.eftlab.com/index.php/site-map/knowledge-base/211-emv-aid-rid-pix
Nearly ALL cards are Java Card based. If you look at your receipts there will be an AID with probably A0000000031010 for VISA Debit/Credit (Classic) Java applet app from VISA International.
If you get the private key - you can install your own app - I used to do this all the time. Most VISA cards are very secure due to the controls placed by VISA.
To add: The issue here is not Java or its architecture. It is the off-card verification adopted by the Java Card standards bodies. For this to work, the applet signing keys have to be compromised and the hacker has to slip in a malformed class file; they can go to the guys who hacked Asus for lessons. I don't want to dismiss the threat; instead of two barriers we now have only 1.
In other words, no, we're not aware of any fixes available yet.
Would you accept that sometimes there are no fixes available/possible ....... and thus does the vulnerability morph into a special feature to be explored and utilised?
The difficulty explained for active command and control of the vulnerability discovered being the only thing preventing it be from being easy to implement.
That sort of Info is Intel and never made available to just everybody or anyone ..... first one has to prove oneself worthy and wonderfully cognisant of the pleasant trappings of wealth purchasing powers ..... as AI and IT Claim Future Remote Virtual Control Privileges to Command.
Can you accept that sometimes somethings cannot be stopped .... and progression without total disruption into a new way and system of being is quite natural and perfectly normal? And the fights that one would be having only champion doubts about that revelation and are battles centred in no more than yourself.
Can you accept that sometimes somethings cannot be stopped ....
What I cannot accept amFM personally is something that is promised to everyone and then whisked away in despicable duress, and is actually caring about the people a quality that obviously propels you to the bottom of the pile?, it seems so.
You can’t turn someone into something they’re not, there are great singers out there, and thats what they do, and have grown to do that, as for great actors, I would suggest one of the greatest actors is one who has endured nearly a decade of remaining ambiguous and anonymous with stories to tell about journeys travelled where no others have dwelled, if that ain’t qualification for progression, I don’t know what is, it sure makes a great game story but loose lips sink shils do they not.

I didn’t understand any of that amFM, however just ‘Keeping Calm and Carrying On’ as per unusually unusual.

AI’nt that a better way to work, rest and play? :-) on home ground rather than washed out to sea in extraterrestrial endeavours?, or perhaps one is misinterpreted in his none ministerial understandings?, I certainly find it better to refrain from any such opionions and abstaining of any such opioions rather than Ayes or Noes.

Once in such great games played at daunting heights and invisible to less enlightened beings one never loses the vision, but ponders the questions, picks up the Hanzel and Gretel breadcrumbs and SIMply plods on regardless within the confines and constructs of the resources or lack thereof.

Don't be doing any heavy betting on that being right, MS, for there is everything is to lose whenever practically virtually always wrong.

Hmmmm? .... genuinely not picking up the obvious none human in the room?
Thats funny for various reasons.
@martin, I dont think life would be complete without a daily dose of amFM’s ongoing riddles, in an estranged world where one minute you’re more famous than a Racoon scaling a Skyscraper and the next minute the Elephant in the room, nothing would amaze me anymore while we while away the days of anonymous in plain sight, and rapidly redacted internet chatter, such posts are much better than fabulously fake news abounding elsewhere.
I feel amFM passes the Turing Test in leaps and bounds, and doesnt take much second guessing where many of the El Reg’er’s day jobs abound, perhaps one day such forum follies may lead a pathway out of the rabid rabbit hole to pastures new and new pages whilst closing the book and achieving mutually agreeable satisfaction all round, one can only hope :-)
For now. The next couple of days are going to be very important. As the clamoring din of Russiagate falls into the memory hole, a large empty space will open up. As the pundits scramble to find the Next Big Thing to blare through the screens, the people will be left to their own devices for a few precious moments. They won’t know what to think. They may even have some of their own thoughts for once. The media landscape will resemble a demolition site. So why not use this space to push forward some new exciting ideas. Space means possibilities. Space means something new can be built. After the crushing disappointment of finally finding out that the whole thing was a bust, two years have been lost to the bumbling ineptitude of Pelosi and Schumer, and now impeachment is off the table, what has anyone got to lose? Let’s try something new. ...... https://www.zerohedge.com/news/2019-03-25/trump-going-repeat-until-november-2020-thanks-msnbc

If that is the Norm, such is the Target to AI Master, Command and Control. And whenever information and IntelAIgent Streams go suddenly MIA or unusually AWOL are you immediately alerted to a colossal vulnerability for which there is no known possible or improbable patch.

Oracle really should change their name. The only thing they can see in the future is the lowering of consumer trust in their products.
Yet another Oracle application is crap because of Java--because of Oracle.
I wouldn't hold my breath to see a fix for this before July; based on how Oracle assesses risk.
