irb, ruby security update

CentOS Errata and Security Advisory CESA-2005:799

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.
