bsd_mail(1) (/usr/sbin/Mail)
Systems Affected:IRIX 3.3 and 3.31
Problem: /usr/sbin/Mail can fail to reset its group id to the group id of the caller. Can allow any user logged onto the system to read any other user's (including root's) mail.
Solution: A fixed /usr/sbin/Mail binary has been made available for anonymous ftp from SGI.COM ([192.48.153.1]). The correct binary can be found at:

sgi/Mail/Mail

under the ftp directory.

Note that this binary must be installed with the same group (mail) and permissions (2755) as your existing 3.3 or 3.3.1 /usr/sbin/Mail.
