That exploit is relevant only on a multi-user linux/bsd system. It's a privilege escalation exploit, i.e. it allows a non-root user to become root.
This has actual bad effects (in terms of access to user data) only on a system with more than one non root user, which does not include the vast majority of desktop/laptops.

Furthermore, the exploit will be closed in the next calibre release.
