Corrupção de memória genérica

Fraqueza genérica que descreve quando software escreve dados fora dos limites esperados de um buffer ou estrutura de memória, sobrescrevendo dados adjacentes. Permite ao atacante corromper dados críticos, executar código arbitrário ou derrubar a aplicação.

Ejemplo

Um programa C que copia uma string do usuário para um array fixo sem validar comprimento: strcpy(buffer, user_input) em um buffer de 64 bytes, quando o input tem 200 caracteres. Os dados transbordados sobrescrevem variáveis, ponteiros ou endereços de retorno na pilha.

Cómo mitigar

Use funções seguras de cópia (strncpy, strlcpy, memcpy com tamanho validado), implemente validação de entrada e comprimento antes de qualquer operação de escrita em buffer, e ative proteções de compilador como stack canaries e ASLR. Em linguagens modernas (Rust, Go), o gerenciamento automático de memória elimina essa classe de bugs.
