Fallos del tipo CWE-787
5232 resultadosEscrita fora dos limites de memória
Ocorre quando um programa escreve dados em uma posição de memória fora do intervalo alocado para um buffer, array ou estrutura. O atacante aproveita para sobrescrever dados adjacentes (variáveis, ponteiros, pilha de retorno), alterando o comportamento da aplicação ou assumindo controle total do sistema.
Ejemplo
Um programa lê 256 bytes de entrada do usuário e copia para um buffer de 64 bytes sem validação. O atacante envia 300 bytes, que transbordam o buffer e sobrescrevem o endereço de retorno na pilha, permitindo execução de código arbitrário.
Cómo mitigar
Sempre validar tamanho de entrada contra o limite do buffer antes de copiar (usar strncpy, snprintf em vez de strcpy, sprintf). Em linguagens modernas, usar estruturas bounds-checked (Rust, C# arrays) ou linters que detectem padrões perigosos.
