Prior to versions 6.3.1 and 5.6.7, puma exhibited incorrect behavior when parsing chunked transfer encoding bodies and zero-length Content-Length headers in a way that allowed HTTP request smuggling. Severity of this issue is highly dependent on the nature of the web site using puma is. This could be caused by either incorrect parsing of trailing fields in chunked transfer encoding bodies or by parsing of blank/zero-length Content-Length headers. Both issues have been addressed and this vulnerability has been fixed in versions 6.3.1 and 5.6.7. Users are advised to upgrade. There are no known workarounds for this vulnerability."}, {"lang": "es", "value": "Puma es un servidor web Ruby/Rack construido para paralelismo. Antes de las versiones 6.3.1 y 5.6.7, Puma mostraba un comportamiento incorrecto al analizar cuerpos de codificaci\u00f3n de transferencia en trozos y cabeceras Content-Length de longitud cero de forma que permit\u00eda el contrabando de peticiones HTTP. La gravedad de este problema depende en gran medida de la naturaleza del sitio web que utiliza Puma. Esto podr\u00eda ser causado por un an\u00e1lisis incorrecto de los campos finales en los cuerpos de codificaci\u00f3n de transferencia en trozos o por el an\u00e1lisis de cabeceras Content-Length en blanco/longitud cero.
