Problem executing setuid script in perl-5.8.6
Hi,

I have a script (a.pl) that can be run by anyone. The script internally has to read a file and write into few files which are owned by user 'myUser'.

Has to read the following file:
-rwx------ 1 myuser myuser 4986 Aug 20 18:11 my.file
Has to write into following files:

-rw-rw-r-- 1 myuser myuser 2187 Aug 21 15:11 a.log
-rw-rw-r-- 1 myuser myuser 0 Aug 20 17:53 b.log
-rw-rw-r-- 1 myuser myuser 4933 Aug 20 17:57 v.log

So, I have made a.pl as setuid script. It used to work fine in perl-5.6.1
In perl-5.8.6, it started to throw the following famous fatal error
"Insecure dependency at system ...." where i use system() to execute a java class.

system "/usr/local/java/jdk1.5/bin/java", "mypackage.mysubpackage.MyClass";

Could somebody help me out either by suggesting a different approach to accomplish the above task or mentioning a workaround for executing setuid scripts in perl-5.8.6?

thanks in advance,
Sarma.

service

service(8)						      System Manager's Manual							service(8)

NAME

       service - run a System V init script

SYNOPSIS

       service SCRIPT COMMAND [OPTIONS]

       service --status-all

       service --help | -h | --version

DESCRIPTION

       service	runs a System V init script in as predictable an environment as possible, removing most environment variables and with the current
       working directory set to /.

       The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT.  The  supported  values  of  COMMAND  depend  on  the
       invoked	script.  service passes COMMAND and OPTIONS to the init script unmodified.  All scripts should support at least the start and stop
       commands.  As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start  com-
       mand.

       service --status-all runs all init scripts, in alphabetical order, with the status command.

EXIT CODES

       service calls the init script and returns the status returned by it.

FILES

       /etc/init.d
	      The directory containing System V init scripts.

ENVIRONMENT

       LANG, TERM
	      The only environment variables passed to the init scripts.

SEE ALSO

       /etc/init.d/skeleton,
       update-rc.d(8),
       init(8),
       invoke-rc.d(8).
