Hello and welcome to the Friday, September 15, 2023 edition of the Sansonet Stormer's Stormcast.

My name is Johannes Ulrich and today I'm recording from Jacksonville, Florida.

Ever wanted to debug software that was created for the Raspberry Pi on your X-86 Windows systems.

The challenge here is that not only do you need to run Linux on your Windows system,

that's pretty straightforward with Virtual Machine or the Windows subsystem for Linux,

but you also need to emulate the different architectures as Raspberry Pi's are

using ARM. One of our undergraduate interns now came up with a solution using QEMU.

QEMU is different from virtualization. It actually emulates a different hardware, and as such is able to emulate a Raspberry Pi arm

processor on your x86 Windows workstation.

Emulation is not a high performance solution, but certainly sufficient for things like debugging

where sometimes slower performance is actually preferred,

thanks to our intern Alan Engel for providing the detailed instructions.

If you ever used tools on the Linux command line, you may have run into tools that sort of display dialogue boxes

or even something that resembles Windows on a text-based terminal. In order to create these

effects, the software likely used a library called N curses, which is short for new curses.

So this is a library that you find on every single Unix system, probably even some

Windows versions or so on that, of that library that you may run into, and Microsoft now

published details regarding a set of different vulnerabilities that affect this library.

These vulnerabilities have been disclosed.

Patches have been made available.

But given that we now have more details available, you certainly need to make sure that everything is patched and up to date.

The vulnerabilities can lead to remote code execution.
