RHEL 2.1 / 3 / 4 : ruby (RHSA-2006:0729)

Medium Nessus Plugin ID 23679


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


Updated ruby packages that fix a denial of service issue for the CGI instance are now available.

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 multipart/form-data MIME data. If a remote attacker sends a specially crafted multipart-form-data request, it is possible to cause the ruby CGI script to enter an infinite loop, causing a denial of service.

Users of Ruby should upgrade to these updated packages which contain backported patches and are not vulnerable to these issues.


Update the affected packages.
