scponlyc in scponly 4.1 and earlier, when the operating system supports LD_PRELOAD mechanisms, allows local users to execute arbitrary code with root privileges by creating a chroot directory in their home directory, hard linking to a system setuid application, and using a modified LD_PRELOAD to modify expected function calls in the setuid application.
