Descriptions
Rack before 1.1.3, 1.2.x before 1.2.5, and 1.3.x before 1.3.6 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.
Rack anterior a v1.1.3, v1.2.x anterior a v1.2.5, v1.3.6 y v1.3.x calcula los valores hash de los parámetros de forma, sin restringir la capacidad de desencadenar colisiones hash predecible, lo que permite a atacantes remotos provocar una denegación de servicio (CPU consumo) mediante el envío de gran cantidad de parámetros a mano.
The update of librack-ruby in DSA-2783-1 also addressed CVE-2013-0183. The patch applied breaks rails applications like redmine (see Debian Bug #727187). Updated packages are available to address this problem.
