Exploit públicoDisponiblePublicado en Exploit-DB
El sistema de recursos de PHP versión 5.0.0 hasta 5.2.1 permite a los atacantes dependiendo del contexto ejecutar código arbitrario mediante la interrupción de la función hash_update_file por medio de (1) un error de espacio de usuario o (2) controlador de secuencias, que luego puede ser utilizado para destruir y modificar recursos internos. NOTA: más tarde se reportó que PHP versiones 5.2 hasta 5.2.13 y 5.3 hasta 5.3.2 también se ven afectadas.
