Subject:  Executing suid scripts



Hi, am running into a problem running a sybperl script with the user setid bit
on.

The script has to be run with the user setid bit on. The permissions are 4711:

[2] ls -al killspid.pl
-rws--x--x   1 sybase   sybase       575 Oct 31 11:54 killspid.pl

When I try to execute this script as another user, I get the following:

pm_repo46@hrdev:[1] /home/sybase/killspid.pl
Can't load
'/usr/local/perl/5.2.0.2/solaris/lib/site_perl/sun4-solaris/auto/Sybase/DBlib/DBlib.so'

for module Sybase::DBlib: ld.so.1: /usr/local/bin/perl: fatal: libsybdb.so: open
failed: No such file or directory at
/usr/local/perl/5.2.0.2/solaris/lib/DynaLoader.pm line 140.

 at /usr/local/perl/5.2.0.2/solaris/lib/site_perl/Sybase/DBlib.pm line 304
BEGIN failed--compilation aborted at
/usr/local/perl/5.2.0.2/solaris/lib/site_perl/Sybase/Sybperl.pm line 43.
BEGIN failed--compilation aborted at
/usr/local/perl/5.2.0.2/solaris/lib/site_perl/sybperl.pl line 16.


The PATH, SYBASE, LD_LIBRARY_PATH path variables are the same as the owner of
the script.

If I change the permissions on the script to 0755, I have no problems.

pm_repo46@hrdev:[3] /home/sybase/killspid.pl
killed spid 43

The script needs to have read permissions revoked from the group/world. Hence,
the reason for setting the permissions as 4711

Any idea what could be wrong? Any help is highyly appreciated.


TIA
