Environments designed to analyze the behavior of different memory allocator implementations.
Distinct from C Heap Allocators: The candidates are either the allocators themselves or specific interceptors, not the environment for testing them.

how2heap is an educational resource and technical testbed for learning heap-based vulnerabilities and memory allocator internals. It provides a collection of source code examples and binaries that serve as a laboratory for studying memory corruption techniques specifically targeting the glibc malloc implementation. The project focuses on the development of exploit primitives, such as tcache poisoning and double frees, to redirect program execution. It includes a suite of implementations for bypassing memory protections and manipulating heap metadata to achieve arbitrary memory writes. The fr
Ships a containerized environment for compiling and analyzing how different glibc versions handle heap allocations.
