Well this is one hell of a linux security bug to have gone unnoticed for so long.

Bad that it's been around so long, but it really doesn't look that bad. On every server I've checked, the condition that it exploits is not present. Perhaps I'm just not on larger multi-user systems where the admins have granted limited root access to certain accounts.
