Summary

Ruby is an interpreted scripting language for quick and easy 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-2008-3655)
A denial of service flaw was found in Ruby's regular expression engine. If a Ruby script tried to process a large amount of data via a regular expression, it could cause Ruby to enter an infinite-loop and crash. (CVE-2008-3443)
Users of ruby should upgrade to these updated packages, which contain backported patches to resolve these issues.
