/usr/bin/solstice is a program launcher under solaris 2.5
Unfortunately, for some reason, it is distributed set-gid bin,
and politely launches any programs without revoking this.
(ignore any warnings/errors along the way)
click Add Applications
fill in any arbitary things for the fields, stick the program
you want to run as setgid bin (or create a sgid shell)
click on the icon which appears with your app name.
As an aside, is there any reason why Solaris distributes
with so many important (like /etc and /bin) as writable by
group? This really converts a lot of not-so-dangerous
set-gid vulnerabilities to root vulnerabilities.
Here is patch information:

This is a well known bug which has already been discussed here at length.
/usr/bin/solstice was first shipped with SOlaris 2.5/SunOS 5.5 so older
versions are not at risk.
These patches fix the bug, alternatively you can just remove the set-gid bit.
