CentOS 3 / 4 / 5 : vixie-cron (CESA-2007:0345)

low Nessus Plugin ID 25254

Synopsis

The remote CentOS host is missing a security update.

Description

Updated vixie-cron packages that fix a denial of service issue are now available.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

The vixie-cron package contains the Vixie version of cron. Cron is a standard UNIX daemon that runs specified programs at scheduled times.

Raphael Marichez discovered a denial of service bug in the way vixie-cron verifies crontab file integrity. A local user with the ability to create a hardlink to /etc/crontab can prevent vixie-cron from executing certain system cron jobs. (CVE-2007-1856)

All users of vixie-cron should upgrade to these updated packages, which contain a backported patch to correct this issue.

Solution

Update the affected vixie-cron package.
