3. Problem description:

Ruby is an interpreted scripting language for object-oriented programming.

A bug was found in the way ruby handles eval statements. It is possible for a malicious script to call eval in such a way that can allow the bypass of certain safe-level restrictions. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-2337 to this issue.

Users of Ruby should update to these erratum packages, which contain a backported patch and are not vulnerable to this issue.

4. 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, launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate RPMs being upgraded on your system.

5. Bug IDs fixed (http://bugzilla.redhat.com/):
