I want to make sure that nobody changed a file. In order to accomplish that, I want not only to check MD5 sum of the file, but also check its size, since as far as I understand this additional simple check can sophisticate falsification by several digits.
May I trust the size that stat
returns? I don't mean if changes were made to stat
itself. I don't go that deep. But, for instance, may one compromise the file size that stat
returns by hacking the directory file? Or by similar means, that do not require superuser privileges?
It's Linux.
