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.
