Descriptions

lib/rack/multipart.rb in Rack before 1.1.4, 1.2.x before 1.2.6, 1.3.x before 1.3.7, and 1.4.x before 1.4.2 uses an incorrect regular expression, which allows remote attackers to cause a denial of service (infinite loop) via a crafted Content-Disposion header.

lib/rack/multipart.rb en Rack anterior a v1.1.4 anterior a v1.1.5, v1.2.x anterior a v1.2.6, v1.3.x anterior a v1.3.7, y v1.4.x anterior a v1.4.2, emplea incorrectamente las expresiones regulares lo que permite a atacantes remotos provocar una denegación de servicio (bucle infinito) a través de una cabecera manipulada del tipo Content-Disposion.
