thanks for all the replies, I really appreciate this.

Ok I should have been more precise in my previous mail. In this scenario I
don't have control over the output generated by the find command. So
basically the cronjob is something like:
15 4 * * 6 root /usr/bin/find /home/userA -type f -print > /tmp/report.txt
Consequently as userB I have no way of influencing what information is printed
by the find command to /tmp/report.txt but I can surely
control /tmp/report.txt. Any other ideas of how to exploit this to gain root
Thank you very very much.
All the best,
