=> ↺ cURL audit: How a joke led to significant findings
While discussing the threat model of the application, one of our team members jokingly asked, “Have we tried curl AAAAAAAAAA… yet”? Although the comment was made in jest, it sparked an idea: we should fuzz cURL’s command-line interface (CLI). Once we did so, the fuzzer quickly uncovered memory corruption bugs, specifically use-after-free issues, double-free issues, and memory leaks. Because the bugs are in libcurl, a cURL development library, they have the potential to affect the many software applications that use libcurl. This blog post describes how we found the following vulnerabilities: [...]
=> ↺ OpenSPICE: A Portable Python Circuit Simulator
[Roman Parise] and [Georgios Is. Detorakis] have created OpenSPICE a fork of the PySpice project, adding a new simulation engine written entirely in Python. This enables the same PySpice simulations to be executed on any platform that runs python (which we reckon is quite a few!) whilst leveraging the full power of the python infrastructure. Since it is a fork — for supported platforms — you can also run your simulations upon Ngspice as well as Xyce, giving options for scaling up to larger systems when required, but importantly without having to recreate your circuit from scratch.

CircuitPython has a number of “ports” that are the core implementations for different microcontroller families. Stability varies on a per-port basis. As of this release, these ports are consider stable: [...]
