From Red Hat Security Advisory 2007:0961 :

Updated ruby packages that fix several security issues are now available for Red Hat Enterprise Linux 4.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

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

A flaw was discovered in the way Ruby’s CGI module handles certain HTTP requests. If a remote attacker sends a specially crafted request, it is possible to cause the ruby CGI script to enter an infinite loop, possibly causing a denial of service. (CVE-2006-6303)

An SSL certificate validation flaw was discovered in several Ruby Net modules. The libraries were not checking the requested host name against the common name (CN) in the SSL server certificate, possibly allowing a man in the middle attack. (CVE-2007-5162, CVE-2007-5770)

Users of Ruby should upgrade to these updated packages, which contain backported patches to resolve these issues.
