Summary
An analysis of security of the glibc heap
Abstract
Ben discusses his work on securing the Gnu C library, and reviews how the allocator works, talks about how its structure makes it exploitable in some circumstances, and explores some of the hardening patches he's submitted and how they fix some of these problems.
Ben has previously given talks at BLU on Differential Fuzzing (2024-01-17) and Reproducible Builds and Deployments with NixOS (2022-10-19).
