### Description

Oracle Glassfish 2.1.1, 3.0.1, and 3.1.1, as used in Communications Server 2.0, Sun Java System Application Server 8.1 and 8.2, and possibly other products, 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, aka Oracle security ticket S0104869.
