1. Summary:

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64

3. Problem description:

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.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.  

This update is available via Red Hat Network.  Details on how to use
