| Problem Description |
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.
