Estouro ou Envolvimento de Inteiro

Ocorre quando uma operação aritmética produz um resultado que excede a capacidade máxima (ou mínima) do tipo de dado inteiro, causando um envolvimento (wraparound) silencioso para um valor inesperado. O perigo está em decisões lógicas baseadas nesse valor corrompido — validações de tamanho, cálculos de alocação de memória ou verificações de limites falham silenciosamente.

Ejemplo

Um aplicativo valida que um tamanho de upload é menor que 2GB comparando `size < 2147483648`. Um atacante fornece um valor de 2147483648 bytes em um inteiro de 32 bits com sinal; o valor sofre wraparound para -2147483648, passa na validação, e a alocação subsequente falha ou aloca memória insuficiente, levando a corrupção de heap.

Cómo mitigar

Use verificações explícitas antes de operações: validar se a adição de dois números não vai ultrapassar o limite antes de somar, preferir tipos sem sinal quando o contexto permite valores positivos apenas, ou usar bibliotecas/linguagens com aritmética segura que lançam exceções em overflow (como Python ou linguagens modernas com verificação de bounds).
