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)
