## What it is
A free online book (with PDF/ePUB/Mobi editions) explaining glibc heap internals and heap exploitation attacks. It targets readers unfamiliar with the topic as well as security researchers wanting a refresher.

## Use cases
- learn how glibc malloc and free work internally
- get started with heap exploitation
- understand heap memory attacks like use-after-free
- revise heap exploitation techniques before a CTF
- find secure coding guidelines to avoid heap vulnerabilities

## When to choose
- you want a concise beginner-friendly introduction to glibc heap internals
- you are a security researcher starting with heap exploitation
- you need a quick reference on classic heap attacks

## When to avoid
- you need coverage of non-glibc allocators (Windows, jemalloc, tcmalloc)
- you want a hands-on exploitation lab or tooling rather than a book
- you need up-to-date coverage of the latest glibc hardening mitigations

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: security, documentation, developer-tools
- domain: security, tutorials, developer-tools
- platform: cross-platform
- tags: heap-exploitation, glibc, malloc, book, binary-exploitation, memory-corruption, linux
