Just a little addition. If I use /sbin/halt, it works. /usr/bin/halt
points to something called consolehelper.
consolehelper - A wrapper that helps console users run system programs
consolehelper in turn uses userhelper (which has the .. in the path
security hole).
Anyway, consolehelper checks /etc/pam.d/ for a file with the name of the
command. In this case that is halt:
auth sufficient /lib/security/pam_rootok.so
auth required /lib/security/pam_console.so
auth required /lib/security/pam_pwdb.so
account required /lib/security/pam_permit.so
What do these things mean? I know that the .so files are basically
compiled c programs that need to be linked in to something, but what do
each of them do?
