Estouro de buffer na pilha

Ocorre quando um programa escreve mais dados em um buffer alocado na pilha do que ele pode conter, sobrescrevendo dados adjacentes (variáveis, endereços de retorno, ponteiros). Um atacante pode explorar isso para executar código arbitrário ou causar travamento.

Example

Um programa lê uma string do usuário com gets() ou strcpy() sem validar o tamanho, copiando 500 bytes para um buffer de 64 bytes. O excesso sobrescreve o endereço de retorno da função, permitindo desviar a execução para código malicioso.

How to mitigate

Use funções seguras (strncpy, fgets, snprintf) que aceitam limite de bytes; implemente verificações de limites explícitas no código; ative proteções do compilador/SO (stack canaries, DEP/NX, ASLR); use linguagens com verificação automática de limites ou ferramentas de análise estática.
