Prior to Apache CXF 4.2.3 and 4.1.8 and 3.6.12, there was no default placed on this size, meaning that a denial of service attack is possible if the user doesn't explicitly set the limit. Users should update to Apache CXF 4.2.3 or 4.1.8 or 3.6.12 which fixes this problem by imposing a default attachment size limit of 50mb."

Antes de Apache CXF 4.2.3, 4.1.8 y 3.6.12, no había un valor predeterminado establecido para este tamaño, lo que significa que un ataque de denegación de servicio es posible si el usuario no establece explícitamente el límite. Los usuarios deben actualizar a Apache CXF 4.2.3 o 4.1.8 o 3.6.12, que soluciona este problema al imponer un límite de tamaño de adjunto predeterminado de 50 MB."
