Keynote: Uninitialized Uses in C++ Programming: The Bytes Before the C++ Types - JF Bastien - C++Online 2024
An in-depth exploration of a subtle aspect of systems programming: uninitialized memory. What are in the bytes before a type exists? This talk dives into the complex world of uninitialized variables, unraveling its mysteries and practical implications. We’ll discuss software security with concrete examples of security vulnerabilities such as information leaks, attacker-controlled values, and use-after-free; performance impact is then explained in-depth; finally, we’ll present mitigations and best practices. The talk delves into memory management on the stack and heap memory, explaining how uninitialized memory issues manifest in each.
