high Nessus Plugin ID 34464

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.

Solution

Update the affected packages.
