Details

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.


Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via Red Hat Network. To use Red Hat Network,

RPMs being upgraded on your system.
