Descriptions

java/org/apache/coyote/http11/InternalNioInputBuffer.java in the HTTP NIO connector in Apache Tomcat 6.x before 6.0.36 and 7.x before 7.0.28 does not properly restrict the request-header size, which allows remote attackers to cause a denial of service (memory consumption) via a large amount of header data.

java/org/apache/coyote/http11/InternalNioInputBuffer.java en el conector HTTP NIO en Apache Tomcat v6.x antes de v6.0.36 y v7.x antes de V7.0.28 no restringe correctamente el tamaño de la petición de cabecera, lo que permite a atacantes remotos causar una denegación de servicio (por excesivo consumo de memoria) a través de una gran cantidad de datos en una cabecera.
