--- layout: post title: "Lecture: Stack Smashing" tags: Lecture description: Slides from a lecture on low-level software exploits and defenses --- Not much to say about recent work, but I'd like to share a lecture I wrote for the honors section of the [systems programming course](https://cs.illinois.edu/courses/profile/CS241) I am helping teach. It's a broad overview on [stack buffer overflow](https://en.wikipedia.org/wiki/Stack_buffer_overflow) exploits and common defenses, for the newbie systems programmer, with a few pretty diagrams that I spent way too much time on... (Apologies about the PDF viewer if it's not looking quite right. [You can view the slides directly](/static/content/stack-smashing.pdf).)
