RHEL 4 : ruby (RHSA-2006:0427)

Medium Nessus Plugin ID 21366


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


Updated ruby packages that fix a denial of service issue 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 bug was found in the way Ruby creates its xmlrpc and http servers.
The servers use a non blocking socket, which enables a remote user to cause a denial of service condition if they are able to transmit a large volume of information from the network server. (CVE-2006-1931)

Users of Ruby should update to these erratum packages, which contain a backported patch and are not vulnerable to this issue.


Update the affected packages.
