Estouro de buffer clássico

A aplicação copia dados para um buffer sem validar o tamanho, permitindo que um atacante sobrescreva memória adjacente, incluindo endereços de retorno ou ponteiros de função. Isso resulta na execução de código arbitrário com os privilégios da aplicação.

Example

Um programa lê uma entrada do usuário com gets() ou strcpy() sem limitar quantos bytes podem ser copiados. Um atacante fornece uma entrada maior que o buffer, sobrescrevendo a pilha e injetando código malicioso que será executado quando a função retornar.

How to mitigate

Use funções seguras que validam limites (strncpy, snprintf, fgets) e compile com proteções de pilha ativadas (-fstack-protector-all no GCC). Além disso, implemente validação de entrada no tamanho esperado e considere linguagens com gerenciamento automático de memória para novos projetos.
