Descriptions

org/apache/tomcat/util/net/NioEndpoint.java in Apache Tomcat 6.x before 6.0.36 and 7.x before 7.0.28, when the NIO connector is used in conjunction with sendfile and HTTPS, allows remote attackers to cause a denial of service (infinite loop) by terminating the connection during the reading of a response.

org/apache/tomcat/util/net/NioEndpoint.java en Apache Tomcat v6.x antes de v6.0.36 y v7.x antes de V7.0.28, cuando el conector NIO se utiliza junto con sendfile y HTTPS permite a atacantes remotos provocar una denegación de servicio (bucle infinito) terminando la conexión durante la lectura de una respuesta.

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.
