South Korean President Yoon Suk Yeol Impeached Over Martial Law Decree

2024-12-14

South Korea's parliament impeached President Yoon Suk Yeol on Saturday over his controversial six-hour-long martial law declaration. The National Assembly voted 204-85 in favor of impeachment, suspending Yoon's powers and duties. Prime Minister Han Duck-soo assumed presidential authority. The Constitutional Court has 180 days to decide whether to remove Yoon from office; a new election would follow within 60 days if he is dismissed. The impeachment followed days of political turmoil and widespread protests, with public opinion overwhelmingly in favor of removing Yoon. While Yoon declared the martial law as a measure against the opposition, his actions are seen by many as an attempt to undermine democratic processes. The US and Japan expressed support for South Korea's democratic process.

Security Vulnerabilities Stemming from Dart/Flutter's Weak PRNG

2024-12-13

Zellic's research uncovered multiple security vulnerabilities caused by a weak pseudorandom number generator (PRNG) in Dart/Flutter. A flaw in the initialization of the `Random()` function within the Dart SDK resulted in insufficient entropy in generated keys, making them susceptible to brute-force attacks. This allowed attackers to easily gain access to the Dart Tooling Daemon, enabling them to read or write workspace files and even execute arbitrary code. Furthermore, Proton Wallet and SelfPrivacy projects were also affected by this weak PRNG, experiencing encryption vulnerabilities and predictable password issues, respectively. While the vulnerability has been patched, developers are urged to exercise caution when using the `Random()` function and utilize `Random.secure()` when cryptographically secure random numbers are required.

Unveiling the Deep Connection Between Maximum Likelihood Estimation and Loss Functions

2024-12-15

This article delves into the intrinsic relationship between Maximum Likelihood Estimation (MLE) and commonly used loss functions. Starting with the fundamentals of MLE, the author meticulously explains its close connection to KL divergence. The article then uses Mean Squared Error (MSE) and Cross-Entropy as examples, demonstrating how these functions are naturally derived from MLE rather than being arbitrarily chosen. By assuming data distributions (e.g., Gaussian for linear regression, Bernoulli for logistic regression), maximizing the likelihood function via MLE directly leads to MSE and Cross-Entropy loss functions. This provides a clear path to understanding the theoretical underpinnings of loss functions, moving beyond mere intuition.

WASM Program Bypasses node:wasi Filesystem Sandbox

2024-12-15

This project demonstrates a proof-of-concept showcasing how a WASM program can bypass the preopens directory restriction in node:wasi to access files outside the sandbox. Normally, WASM programs are limited to accessing pre-opened directories. However, by cleverly using symbolic links to replace files at a precise moment and running an external process, this limitation can be circumvented. This is not a practical security vulnerability in node:wasi, but rather a potential edge case. The project highlights that one shouldn't rely on node:wasi to completely prevent malicious code from accessing external files.
