Estouro de heap

Ocorre quando código escreve mais dados do que o espaço alocado em uma região de memória dinâmica (heap), sobrescrevendo dados adjacentes. Um atacante pode explorar isso para corromper estruturas de dados críticas, contornar proteções de segurança ou executar código arbitrário.

Exemplo

Um servidor web aloca 256 bytes para armazenar um nome de usuário, mas copia 512 bytes de uma requisição sem validação. Os 256 bytes extras sobrescrevem ponteiros ou metadados do heap, permitindo execução de código ou negação de serviço.

Como mitigar

Use funções seguras que respeitam limites (strcpy_s, memcpy com tamanho verificado em runtime). Validar e limitar o tamanho de entrada antes de copiar. Ativar proteções como ASLR, stack canaries e ferramentas de sanitização (AddressSanitizer) em desenvolvimento.
