Apache Tomcat 6.x before 6.0.37 and 7.x before 7.0.30 does not properly handle chunk extensions in chunked transfer coding, which allows remote attackers to cause a denial of service by streaming data.

Apache Tomcat v6.x anteriores a v6.0.37 y v7.x anteriores a v7.0.30 no gestionan de forma adecuada las extensiones troceadas, en la transferencia de trozos codificados, lo que permite a atacantes remotos a provocar una denegación de servicio mediante datos en stream.
