irb, ruby security update

CentOS Errata and Security Advisory CESA-2006:0604

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

A number of flaws were found in the safe-level restrictions in Ruby. It
was possible for an attacker to create a carefully crafted malicious script
that can allow the bypass of certain safe-level restrictions. (CVE-2006-3694)

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