Descriptions

In lighttpd 1.4.46 through 1.4.63, the mod_extforward_Forwarded function of the mod_extforward plugin has a stack-based buffer overflow (4 bytes representing -1), as demonstrated by remote denial of service (daemon crash) in a non-default configuration. The non-default configuration requires handling of the Forwarded header in a somewhat unusual manner. Also, a 32-bit system is much more likely to be affected than a 64-bit system.

En lighttpd versiones 1.4.46 hasta 1.4.63, la función mod_extforward_Forwarded del plugin mod_extforward tiene un desbordamiento de búfer basado en la pila (4 bytes que representan -1), como lo demuestra la denegación de servicio remota (caída del demonio) en una configuración no predeterminada. La configuración no predeterminada requiere el manejo de la cabecera Forwarded de una manera algo inusual. Además, es mucho más probable que un sistema de 32 bits se vea afectado que un sistema de 64 bits
