It was reported , that cronie would leak certain fd's. On systems where /etc/crontab is not world-readable this could be an information disclosure concern.
This was introduced upstream in cronie 1.4.8  and fixed in 1.4.9 , so the only version of cronie that is affected by this issue is 1.4.8. It was also patched in Fedora via cronie-1.4.8-2.fc15 (see  for those details).
Not vulnerable. This issue did not affect the versions of cronie as shipped with Red Hat Enterprise Linux 6.
