Checkout 's great writeup on md15 from CTF ( - you rock!) - . Interesting point: if we run this on WSLv1, it's immediately fail (due to different behavior in the loader) on the whole point of the chg, revealing everything ;)

Just got a second exploit and write-up from the CTF! This time from "braindead" 🧠💀 This one combines missing userspace pointer validation in writev() with a TOCTOU in clock_nanosleep(). Great show! 😊👍

In the wake of last week's exploit, I've been auditing the SerenityOS syscalls and found quite a number of terrible and very exploitable bugs. 🐞💣💥 Let me show you some of them!

When you include a file inside of a macro invocation, it seems GCC goes into the included file and fails to finish the macro call there. Clang does not have this problem. Found it during analysis of writeup to 36c3 CTF compilerbot challenge
