Wait a minute, they said the bug could be exploited without logging in?
The original notice said:

]A potential vulnerability has been discovered in the IRIX 5.2 operating
]system which would enable an unprivileged user to become an active
]root user.                                ~~~~

So which is it?

Also, here's one I tried to send out while bugtraq was on hiatus.
/usr/sbin/colorview is setuid root and can be used to read any file on
the system (e.g., /etc/shadow) with the "-text" option.  Affects IRIX
5.2 at least.
