3. Description:

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.

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
the Red Hat Network to apply this update are available at

5. Bugs fixed (http://bugzilla.redhat.com/):
