Peteris Krumins has recently written in his blog a very nice article on basic security of sysadmins. He exploits, or… maybe a better word here is… evaluates a door that is there in ldd for ages, but neverthelesss not many sysadmins are aware of it, while checking user programs with ldd from root account.

This bug-o-feature has been also recently noticed by Debian community, though it is still not present in many heads.

Very nice article to keep your head around hygiene of administering your *nix systems in a responsible way of ‘thinking before doing’.
