Re: POS
I think we should skip EMV and jump to Apple or Google pay directly. It is more secure and convenient.

Dumb POS
Maybe we need to make POS as dumb as possible, so there is a less opportunity to be vulnerability to attacks.

Re: POS
@Ryan: Well, that's the whole problem.  That education *shouldn't* fall to the merchants; it should fall to the credit card companies compelling the switch.

But good luck with that.

Re: POS Exploitation
@Ryan: My feeling is that that's by design -- that many large enterprises have determined the risk worth it compared to the cost.  (Reminds me of how the TJX CIO, prior to their major breach some years back, sent out a memo explicitly saying that it made more budgetary sense to hold off on PCI-DSS compliance -- and outright daring anyone to stand up to him.)

Re: POS
We've all seen the futzing first hand...If merchants don't find a more efficient education process than EMV could lose popularity.

POS Exploitation
It seems that many companies don't take the data threat seriously until they are burnt, especially when it comes to POS...

With the trend of data breaches involving POS, it is irresponsible to handle business as status quo.

POS
The funny thing is that now that EMV cards have been introduced and more stores are taking them, there is a lot of futzing about at points of sale as cashiers attempt to educate consumers on how to insert their new chip card into the new system.

This could make it easier for a bad guy to insert a skimmer into a POS device (and yes, even EMV is vulnerable to skimming and MitM attacks).

CVE-2020-15208
PUBLISHED: 2020-09-25
In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, when determining the common dimension size of two tensors, TFLite uses a `DCHECK` which is no-op outside of debug compilation modes. Since the function always returns the dimension of the first tensor, malicious attackers can ...
CVE-2020-15209
PUBLISHED: 2020-09-25
In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, a crafted TFLite model can force a node to have as input a tensor backed by a `nullptr` buffer. This can be achieved by changing a buffer index in the flatbuffer serialization to convert a read-only tensor to a read-write one....
CVE-2020-15210
PUBLISHED: 2020-09-25
In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, if a TFLite saved model uses the same tensor as both input and output of an operator, then, depending on the operator, we can observe a segmentation fault or just memory corruption. We have patched the issue in d58c96946b and ...
CVE-2020-15211
PUBLISHED: 2020-09-25
In TensorFlow Lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, saved models in the flatbuffer format use a double indexing scheme: a model has a set of subgraphs, each subgraph has a set of operators and each operator has a set of input/output tensors. The flatbuffer format uses indices f...
CVE-2020-15212
PUBLISHED: 2020-09-25
In TensorFlow Lite before versions 2.2.1 and 2.3.1, models using segment sum can trigger writes outside of bounds of heap allocated buffers by inserting negative elements in the segment ids tensor. Users having access to `segment_ids_data` can alter `output_index` and then write to outside of `outpu...
