Description :

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

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.
