Techniques for manipulating memory allocators to achieve unauthorized memory access or control flow redirection.
Distinct from Allocator Redirections: None of the candidates cover heap exploitation; they focus on performance optimization or general allocator implementation.

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
Implements techniques to trick the allocator into returning stack addresses through double-free vulnerabilities.
