Escrita fora dos limites da memória

Ocorre quando o código escreve dados em um endereço de memória fora do intervalo alocado para uma estrutura (array, buffer, objeto). O programa não valida o tamanho ou índice antes de escrever, permitindo sobrescrever memória adjacente — causando corrupção de dados, queda da aplicação ou execução arbitrária de código.

Example

Um formulário web que copia o valor de um campo do usuário para um buffer de 64 bytes sem verificar o comprimento: se o atacante enviar 200 caracteres, a escrita invade a memória vizinha e pode sobrescrever um ponteiro de função ou variável crítica.

How to mitigate

Sempre validar tamanhos de entrada antes de copiar (usar `strncpy` em vez de `strcpy`, ou bibliotecas seguras como `bounds-checking`); usar linguagens com verificação automática de limites (Java, Rust); aplicar testes de fuzzing e análise estática de código para detectar escritas desprotegidas.
