Leitura fora dos limites de memória

Ocorre quando o código tenta ler dados de uma posição de memória fora do intervalo alocado para um buffer ou array. O programa não valida o índice ou tamanho antes de acessar, causando leitura de dados inválidos, corrupção de informações ou revelação de dados sensíveis da memória adjacente.

Exemplo

Um processador de imagem PNG lê 4 bytes de um buffer de 2 bytes para validar uma assinatura, ou uma função copia uma string sem verificar se o índice fornecido pelo usuário extrapola o tamanho real do array. Em ambos os casos, dados fora do escopo pretendido são lidos.

Como mitigar

Sempre validar índices e comprimentos contra os limites reais do buffer antes de qualquer leitura. Usar funções seguras (ex: `strncpy` em vez de `strcpy`, bounds-checking em loops) e implementar testes com entradas extremas (size zero, índices negativos, valores muito grandes).
