The ap_rwrite() function in Apache HTTP Server 2.4.53 and earlier may read unintended memory if an attacker can cause the server to reflect very large input using ap_rwrite() or ap_rputs(), such as with mod_luas r:puts() function. Modules compiled and distributed separately from Apache HTTP Server that use the 'ap_rputs' function and may pass it a very large (INT_MAX or larger) string must be compiled against current headers to resolve the issue.
La función ap_rwrite() en el Servidor HTTP Apache 2.4.53 y anteriores puede leer memoria no intencionada si un atacante puede hacer que el servidor refleje una entrada muy grande usando ap_rwrite() o ap_rputs(), como con la función mod_luas r:puts(). Los módulos compilados y distribuidos por separado del Servidor HTTP Apache que usan la función 'ap_rputs' y pueden pasarle una cadena muy grande (INT_MAX o mayor) deben ser compilados contra las cabeceras actuales para resolver el problema
