Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated ruby packages that fix various security issues are now
available for Red Hat Enterprise Linux 2.1.

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

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.
