Synopsis

The remote CentOS host is missing one or more security updates.

Description

Updated ruby packages that fix a security issue are now available for Red Hat Enterprise Linux 4 and 5.

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

Ruby is an extensible, interpreted, object-oriented, scripting language. It has features to process text files and to do system management tasks.

Vincent Danen reported, that Red Hat Security Advisory RHSA-2008:0897 did not properly address a denial of service flaw in the WEBrick (Ruby HTTP server toolkit), known as CVE-2008-3656. This flaw allowed a remote attacker to send a specially crafted HTTP request to a WEBrick server that would cause the server to use excessive CPU time. This update properly addresses this flaw. (CVE-2008-4310)

All Ruby users should upgrade to these updated packages, which contain a correct patch that resolves this issue.

Solution

Update the affected ruby packages.
