The remote host is missing an update to vixie-cron announced via advisory MDKSA-2007:234.
Raphael Marichez discovered a denial of service bug in how vixie-cron verifies crontab file integrity. A local user with the ability to create a hardlink to /etc/crontab could prevent vixie-cron from executing certain system cron jobs.
The updated packages have been patched to correct this issue.
Affected: 2007.0, 2007.1, 2008.0
Solution: To upgrade automatically use MandrakeUpdate or urpmi. The verification of md5 checksums and GPG signatures is performed automatically for you.
