Estouro de heap

É quando o código escreve dados além dos limites de um buffer alocado no heap (memória dinâmica), sobrescrevendo dados de outras estruturas adjacentes. Esse estouro pode corromper metadados do heap, variáveis vizinhas ou objetos do programa, permitindo execução de código arbitrário ou negação de serviço.

Ejemplo

Um servidor web recebe uma string de tamanho arbitrário e a copia para um buffer de 256 bytes sem validar o comprimento (ex: strcpy em C). Se o atacante enviar 500 bytes, o restante escreve além da zona alocada, corrompendo estruturas próximas e potencialmente ganhando controle do fluxo.

Cómo mitigar

Use funções seguras (strncpy, strlcpy, snprintf em C) que respeitam limites de tamanho; valide e sanitize entrada do usuário antes de copiar; ative proteções do SO (ASLR, DEP/NX); use linguagens de memória segura quando possível; aplique verificações de limites em loops de cópia.
