Corrupção de memória genérica

Fraqueza ampla que descreve qualquer escrita ou leitura inadequada de dados na memória do programa, violando os limites esperados de um buffer, estrutura ou alocação. O risco é grave: pode levar a travamento, execução de código arbitrário ou exposição de dados sensíveis, dependendo de como o atacante explora o acesso descontrolado.

Example

Um programa C lê mais bytes de um array do que deveria (estouro de buffer clássico), ou escreve em endereço de memória inválido após liberar um ponteiro. Em ambos os casos, dados adjacentes são sobrescrevidos ou corrompidos, causando comportamento impredizível ou crash.

How to mitigate

Use verificações de limites antes de qualquer acesso indexado; prefira linguagens com gerenciamento automático de memória (Go, Rust, Python) quando possível; em C/C++, empregue ferramentas como AddressSanitizer em testes e ASLR+DEP/NX em produção para dificultar exploração. Revise ponteiros e aritmética de buffer em code review.
