Mandriva Linux Security Advisory MDKSA-2007:234
http://www.mandriva.com/security/
_______________________________________________________________________

Package : vixie-cron
Date : December 3, 2007
Affected: 2007.0, 2007.1, 2008.0
_______________________________________________________________________

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.
