very good question, when i have seen bugs in sudo, wich allow me to gain root, using sudo su - ,wich is a feature but, if not protected and you have a bad sudo binary 9the sudo -g bug was about time i did tests with the amazon sudo) .. i asked a friend also to do this test and he also gained root thru a non sudo account, because BOTH binarys are there.... i am still baffled with this, i try avoid sudo where i can and, because sudo -g bug was nasty, i try use su - ,wich is abit better i 8think* , but very good question,... id like to know this reasons why to..
