  This is a collision attack, much weaker than pre-image. It means that you can make two different texts with the same hash, but you can't create a text that matches a specific hash. Even MD5 is safe from a pre-image attack, it means, for example, that it is safe to use for storing passwords (but not recommended for other reasons).
