Falhas do tipo CWE-190

1.956 resultados

Estouro ou Envolvimento de Inteiro

Ocorre quando uma operação aritmética produz um valor que excede o limite máximo (ou mínimo) que o tipo de dado inteiro pode armazenar, causando o valor envolver-se para o lado oposto ou comportamento inesperado. Isso permite que atacantes contornem validações, aloquem memória inadequada, ou causem travamentos ao explorar essa descontinuidade.

Exemplo

Um servidor de upload limita arquivos a 2 GB verificando se size < 2147483648 (INT_MAX). Um atacante envia size=2147483648, que em inteiro de 32 bits assinado vira -2147483648. A validação passa, mas durante a alocação de buffer o sistema trata como valor negativo ou inesperado, causando falha ou bypass de proteção.

Como mitigar

Use tipos inteiros sem sinal (unsigned) ou de maior capacidade (64 bits) quando apropriado; valide entradas contra limites explícitos *antes* de operações aritméticas; utilize funções de verificação de overflow fornecidas pela linguagem ou biblioteca (ex: __builtin_add_overflow em C, SafeInt em .NET); evite conversões implícitas entre tipos.
