DjVuLibre has a vulnerability that could enable an attacker to gain code execution on a Linux Desktop system when the user tries to open a crafted document.

In this post, I’ll walk you through the vulnerabilities I uncovered in the GStreamer library and how I built a custom fuzzing generator to target MP4 files.

Learn about the design behind, and solutions to, several of GitHub’s CTF challenge for Ekoparty’s 2022 event!

In this third and last part, I’ll share the results of my research on Apache HTTP server, and I’ll show some of the vulnerabilities that I’ve found.

In this second installment, I will focus on how to build our own custom ASAN interceptors in order to catch memory bugs when custom memory pools are implemented and also on how to intercept file system syscalls to detect logic errors in the target application.

In this first episode, I’ll do a brief introduction on how Apache HTTP works, and I’ll give you some insights into custom mutators and how they can be applied to the HTTP protocol effectively.
