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.
Potential security vulnerabilities have been identified in 3rd party software used in HP XP P9000 Performance Advisor running Oracle and Apache Tomcat Software. HP has updated the Apache Tomcat and Oracle database software to address vulnerabilities affecting confidentiality, availability, and integrity. Revision 1 of this advisory.
