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.
vixie-cron on Mandriva Linux 2007.0, Mandriva Linux 2007.0/X86_64, Mandriva Linux 2007.1, Mandriva Linux 2007.1/X86_64, Mandriva Linux 2008.0, Mandriva Linux 2008.0/X86_64
