Leitura fora dos limites de memória

Quando o código tenta ler dados além do tamanho alocado de um buffer, array ou estrutura de dados. O programa acessa memória que não deveria, podendo vazar informações sensíveis, causar travamento ou ser explorado para executar código arbitrário.

Example

Um validador de imagem PNG que lê o tamanho do chunk do header mas não verifica se esse tamanho é compatível com o arquivo; ao processar, lê bytes da memória adjacente, expondo dados de outras estruturas ou causando crash.

How to mitigate

Sempre validar comprimentos e índices antes de acessar buffers; usar funções seguras (strncpy em vez de strcpy, bounds checking em loops); compilar com sanitizadores (AddressSanitizer, Valgrind) para detectar em tempo de teste.
