Improper file ownership allows user-owned files to be run with root privileges by init scripts.



Background

GIMPS is a client for the distributed Great Internet Mersenne Prime Search. SETI@home is the client for the Search for Extraterrestrial Intelligence (SETI) project. ChessBrain is the client for the distributed chess supercomputer.

Description
==========
