title: Rubinius Hash Collision Form Parameter Parsing Remote DoS
date: 2011-12-28
description: |
  Rubinius contains a flaw that may allow a remote denial of service. The issue
  is triggered when an attacker sends multiple crafted parameters which trigger
  hash collisions, and will result in loss of availability for the program via
  CPU consumption.
