Doing that will give all users the ability to dump the entire process argument list along with the entire process environment - for all processes.
Please don't advise that ...

You also need to be really careful with changing permissions on Solaris base OS binaries - the standard Solaris install hard links multiple utilities to the same underlying binary, so if you change the permissions of one you change them all
Precisely. I just checked on a Solaris 10 update 2 and /usr/ucb/ps code is shared by 62 binaries, including mdb and dtrace (man isaexec to understand why). That means you basically grant root access to anyone with adding the setuid bit to ps.

I guess pkgchk SUNWscpu will tell you. Can you post this command output ?
