Descriptions

The Catalina org.apache.catalina.connector.http package in Tomcat 4.0.x up to 4.0.3 allows remote attackers to cause a denial of service via several requests that do not follow the HTTP protocol, which causes Tomcat to reject later requests.

El paquete Catalina org.apache.catalina.connector.http en Tomcat 4.0.x a 4.0.3 permite a atacantes remotos causar una denegación de servicio mediante ciertas peticiones que no siguen el protocolo HTTP, lo que hace que Tomcat rechace peticiones subsiguientes.
