Raphael Marichez of Gentoo reported a denial of service flaw in vixie-cron.
By creating a hardlink to /etc/crontab, cron will stop executing the
/etc/crontab file and deposit an error message in /var/log/cron.
This can be easily tested by running:
ln /etc/crontab /tmp/crontab
tail -f /var/log/cron
Here is the patch from Open Wall Linux:
This flaw also affects FC5
Thanks for patch. Fixed in vixie-cron-4.1-81
Reopening, as this is an unfixed security issue.
Marcela: please push the fixed version into FC6.
Fixed in update vixie-cron-4.1-69.
