### Description

Apache Geronimo 2.2.1 and earlier computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters.  NOTE: this might overlap CVE-2011-4461.
