This document provides an overview of the glibc heap memory implementation. It discusses the malloc_chunk data structure used to represent memory chunks, as well as malloc_state which tracks heap metadata. It also describes bins which organize free chunks of different sizes, and the core allocation and free functions like malloc, free, and realloc. Finally, it introduces common heap exploitation techniques like double free, use-after-free, and house of cards attacks.
