Descriptions
Ruby (aka CRuby) before 1.8.7-p357 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table.
Ruby (también conocido como CRuby) anterior a v1.8.7-P357 calcula los valores de hash sin restringir la capacidad de desencadenar colisiones hash predecible, que permite a atacantes dependientes de contexto para causar una denegación de servicio (consumo de CPU) a través de entrada diseñado para una aplicación que mantiene un hash mesa.
Multiple vulnerabilities have been found in Ruby, allowing context-dependent attackers to cause a Denial of Service condition. Versions less than 2.0.0_p598 are affected.
