Descriptions

Apache Tomcat 7.0.0 through 7.0.6 and 6.0.0 through 6.0.30 does not enforce the maxHttpHeaderSize limit for requests involving the NIO HTTP connector, which allows remote attackers to cause a denial of service (OutOfMemoryError) via a crafted request.

Apache Tomcat v7.0.0 hasta v7.0.6 y v6.0.0 hasta v6.0.30 no hace cumplir el límite maxHttpHeaderSize de las solicitudes relacionadas con el conector NIO HTTP, que permite a atacantes remotos provocar una denegación de servicio (OutOfMemoryError) a través de una solicitud manipulada.

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.
