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.

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a	Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
