Fuzzing µC/OS protocol stacks, Part 1: HTTP server fuzzing

Fuzzing µC/OS protocol stacks, Part 1: HTTP server fuzzing
This is the first post of a three-part series, where we will be delving into the intricacies of fuzzing µC/OS protocol stacks. The techniques I will discuss are universally applicable to various RTOS environments, though our focus will primarily be on µC/OS.
I’ll highlight some of the strategic code modifications I implemented across different µC/OS components. The objective is to streamline the process of developing a fuzzing harness tailored for the µC/HTTP-server. In the second installment of this series, I’ll discuss a technique that I used for delivering multiple requests per fuzz test case. The third post will be like this one, as I’ll describe the code modifications that I made with the aim of fuzzing the µC/TCP-IP stack.
For a bit of context, µC/OS is an RTOS, or “Real-Time Opera

[HIGH] Vulnerabilities in Adobe Acrobat, Microsoft Excel could lead to arbitrary code execution
## Vulnerabilities in Adobe Acrobat, Microsoft Excel could lead to arbitrary code execution
Cisco Talos’ Vulnerability Research team recently worked with Adobe and Microsoft to patch multiple vulnerabilities in the Acrobat and Excel software, respectively, that could lead to arbitrary code execution.
Talos also disclosed six vulnerabilities in the Weston Embedded µC-HTTP HTTP server implementation, some of which could also lead to code execution.
