Descriptions

The var_export function in PHP 5.2 before 5.2.14 and 5.3 before 5.3.3 flushes the output buffer to the user when certain fatal errors occur, even if display_errors is off, which allows remote attackers to obtain sensitive information by causing the application to exceed limits for memory, execution time, or recursion.

La función var_export en PHP v5.2 anterior a v5.2.14 y v5.3 anterior a v5.3.3 vacía el búfer de salida para el usuario cuando se producen ciertos errores graves, incluso cuando display_errors está apagado, lo que permite a atacantes remotos obtener información sensible provocando que la aplicación exceda los límites de memoria, tiempo de ejecución, o recursividad.
