CVE-2018-18920

Py-EVM v0.2.0-alpha.33 allows attackers to make a vm.executebytecode call that triggers computation.stack.values with '"stack": 100, 100, 0' where b'\x' was expected, resulting in an execution failure because of an invalid opcode. This is reportedly related to "smart contracts can be executed...

CVE-2018-18920

CVE-2018-18920 concerns Py-EVM v0.2.0-alpha.33, where a crafted vm.execute_bytecode call can manipulate computation._stack.values (e.g., "stack": [100, 100, 0]) in a way that expects a certain byte (b'\x') and results in an invalid opcode, causing execution failure. The description ties this to a...

Node.js third-party modules: Prototype pollution attack (smart-extend)

Hi team, I would like to report a prototype pollution vulnerability in smart-extend that allows an attacker to inject properties on Object.prototype. Module module name: smart-extend version: 1.7.3 npm page: https://www.npmjs.com/package/smart-extend Module Description smart-extend is an extensio...

Hacking ghost hunters

We’ve been looking at the security of smart ghost hunting tech. The results were a bit… spooky. TL;DR We bought three devices online. One was a camera for taking photos of ghosts, another was a smart teddy bear for helping ghosts of children apparate, the last a ghost hunting tank camera: In some...

HID ActivID ActivClient 7.1.0.202 Heap Spray / Denial Of Service Vulnerability

HID ActivID ActivClient version 7.1.0.202 may not enforce upper bounds on the size of data received from a smart card, which can lead to attacks such as memory exhaustion, or serve as a heap spraying primitive for other attacks against the software, albeit slowly. HID ActivID ActivClient 7.1.0.20...

HID ActivID ActivClient 7.1.0.202 may not enforce upper bounds on the size of data received from a smart card, which can lead to attacks such as memory exhaustion, or serve as a heap spraying primitive for other attacks against the software, albeit slowly. For example, when running Advanced...

CVE-2018-17877

A lottery smart contract implementation for Greedy 599, an Ethereum gambling game, generates a random value that is predictable via an external contract call. The developer used the extcodesize function to prevent a malicious contract from being called, but the attacker can bypass it by writing t...

CVE-2018-17968

A gambling smart contract implementation for RuletkaIo, an Ethereum gambling game, generates a random value that is predictable by an external contract call. The developer wrote a random function that uses a block timestamp and block hash from the Ethereum blockchain. This can be predicted by...

CVE-2018-17877 concerns a lottery Smart Contract for Greedy 599 (Ethereum). The vulnerability: the contract generates a random value that is predictable through an external contract call. The developer attempted to prevent malicious contracts with extcodesize(), but an attacker can bypass this by...

CVE-2018-7911

CVE-2018-7911 is a Huawei FRP (Factory Reset Protection) bypass vulnerability affecting multiple Huawei smartphone models (e.g., ALP-AL00B, BLA-TL00B, Charlotte-AL00A, Emily-AL00A, etc.) across Android 8.x variants. The root issue, described in Huawei’s advisory and related CNVD/NVD entries, allo...

Are the Police Using Smart-Home IoT Devices to Spy on People?

IoT devices are surveillance devices, and manufacturers generally use them to collect data on their customers. Surveillance is still the business model of the Internet, and this data is used against the customers' interests: either by the device manufacturer or by some third party the manufacture...
