You don't indicate which version of mtink is installed or, rather, which
version of printer-utils is installed.  The issue might be a two-parter,
but the mtink root shell issue was resolved last December with a
printer-utils update as noted in the changelog of the printer-utils
package:

* Thu Dec 29 2005 Stew Benedict <sbenedict@...driva.com> 2006-7.1.20060mdk
- security update for local root vuln in mtink (P103)

If you were not using this version then yes, the advisory would
probably work as indicated.  As a result, with the updated printer-utils
package, you get a "/etc/ld.so.preload: Permission denied" error.

So you really should say that Mandriva has a suitable *unpatched* setuid
binary (not so suitable when you install a nine-month-old update).
