65508: No Longer a Myth: A Guide to Mainframe Buffer Overflows

Project and Program: Service Delivery, Security and Compliance

Tags: Proceedings , SHARE Orlando 2024 , 2024

A brilliant mind recently discovered that what was once thought impossible is now possible. For decades the myth in this community was that they weren't susceptible to buffer overflows, therefore making them safer than their Linux/Windows counterparts. Well it turns out thats not true. This talk will walk through how this was discovered, how to hunt for overflows, especially in APF authorized libraries, and how to exploit them using HLASM and the IBM assembler to make the shellcode for us. This is a very exciting discovery in the mainframe hacker community and we can't wait to share it with you. Attendees will also be given a docker container where they can learn how to write mainframe buffer overflows. -- Presented by Philip Young
