Descriptions

Apache Tomcat 4.1.0 through 4.1.39, 5.5.0 through 5.5.27, and 6.0.0 through 6.0.18, when the Java AJP connector and mod_jk load balancing are used, allows remote attackers to cause a denial of service (application outage) via a crafted request with invalid headers, related to temporary blocking of connectors that have encountered errors, as demonstrated by an error involving a malformed HTTP Host header.

Apache Tomcat v4.1.0 hasta v4.1.39, v5.5.0 hasta v5.5.27 y v6.0.0 hasta v6.0.18, cuando se utilizan el conector Java AJP y el balanceo de carga mod_jk; permite a atacantes remotos provocar una denegación de servicio (caída de la aplicación) a través de una solicitud manipulada con cabeceras inválidas. Está relacionado con el bloqueo temporal de los conectores que han encontrado errores, tal como se ha demostrado por un error que implica una cabecera HTTP Host mal formada.
