"An updated vixie-cron package that fixes a bug and security issue is
now available.

This update has been rated as having low 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.

A bug was found in the way vixie-cron installs new crontab files. It
is possible for a local attacker to execute the crontab command in
such a way that they can view the contents of another user's crontab
file. The Common Vulnerabilities and Exposures project assigned the
name CVE-2005-1038 to this issue.

This update also fixes an issue where cron jobs could start before
their scheduled time.

All users of vixie-cron should upgrade to this updated package, which
contains backported patches and is not vulnerable to these issues."
