The answer is:
Just make your script setuid and you're done. suidperl is required on some
operating systems in order to execute set-uid perl scripts. suidperl used to
be a separate application. On "safe" operating systems (Solaris is considered
safe), you don't need a separate application.

In Solaris all you need to do is make the script set-uid. setuid scripts are
safe on Solaris, so there's no need to use suidperl. suidperl has been created
for use where the OS lacked proper support for setuid scripts, e.g. linux.

Original Post:


I am about to use webmail on my servers. The webmail perl script need
suidperl. I have read faqs about suidperl and have found that in past it had
possessed many flaws which have been exploited to gain unauthorised root
access on the system.

My question is that "is it safe to use suidperl these days?"
Moreover, is there any secure version of suidperl available or should I have
to rely on perl5.004.04's suidperl module. I mean just like wu-ftp which is
far more restricted than solaris's built-in ftp service

Thank you
